15143153	These results indicate that activation of protein kinase c stimulates a kinase which can phosphorylate insulin receptor substrate-1 at serine 612, resulting in an inhibition of insulin signaling in the cell these data suggest that: 1) activation of pkctheta contributes to ikk and jnk activation by ffas;2) ikk and jnk mediate pkctheta signals for irs-1 serine phosphorylation and degradation; ser-302 phosphorylation is dependent on pi 3-kinase/mtor, whereas ser-307 depends on c-jun nh2-terminal kinase to inhibit irs1 tyrosine phosphorylation. Ser-636 is located around the pi 3-kinase binding site and, therefore, thought to inhibit pi 3-kinase signaling.

12682370	Phosphorylation of Kruppel-like factor 5 (KLF5/IKLF) at the CBP interaction region enhances its transactivation function. \| Inhibition of protein kinase activity by H7 or calphostin C blocked both full-length and N-terminal fragment (amino acids 1-238) KLF5 activities. Mutation at a potential protein kinase C phosphorylation site within the CBP interaction domain of KLF5 reduces its transactivation function. Furthermore, using the GST pull-down approach, we showed that phosphorylation of KLF5 enhances its interaction with CBP. The results of the present study provide a mechanism for KLF5 transactivation function. \| We found that KLF5s activity was reduced to half when the serine in the potential PKC phosphorylation site was mutated to alanine (Fig. 6B, S153A) Nonetheless, the S153A mutant still retains significant transactivation activity.

Among several PKC isoenzymes tested, only PKCalpha and -delta were able to specifically phosphorylate Ser(183) in vitro.

The enzymatic activity of pkc-deltas643a mutant as measured by phosphorylating the pkc-delta pseudosubstrate region-derived substrate was also reduced more than 70% in comparison to that of pkc-deltawt.

Phosphorylation of tif1beta/ser473 coincides with the induction of cell cycle gene cyclin a2 at the s-phase. Promoter of cyclin a2 gene is occupied by tif1beta and such occupancy is inversely correlated with ser473 phosphorylation. Non-phosphorylated tif1beta/ser473 allowed greater tif1beta association with the regulatory regions and the consequent repression of these genes.

Expression of a dominant negative pkcdelta or depletion of the endogenous pkcdelta by phorbol 12-myristate 3-acetate treatment abrogates the association of stat3 with gp130. At the same time, pkcdelta is recruited to gp130 via association with stat3, which may facilitate its phosphorylation on the gp130 receptor.

25624455	PTPRG activation by the P1-WD peptide affected the tyrosine phosphorylation of several signaling molecules. Data analysis identified 31 molecules whose phosphorylation was modified in a statistically significant manner (Table I). inhibition of ABL1, BMX, BTK, DAB1, ITGB1, JAK2, KDR, KIT, LIMK1, MET, PDGFRB, SHC1, and VCL correlates with tyrosine dephosphorylation. In contrast, SRC inhibition correlates with hyperphosphorylation of the inhibitory Tyr530 residue and with dephosphorylation of the activatory Tyr419. Moreover, CDK2 and CTTN inhibition correlates with a hyperphosphorylation of the inhibitory Tyr15 and Tyr470, respectively. In contrast, a subgroup of 13 proteins, including BLNK, DOK2, ERBB2, GRIN2B, INSR, PDGFRA, PRKCD, PXN, STAT1, STAT2, STAT3, STAT5A, and ZAP70, appears to be activated by PTPRG activity.

11381116	The tyrosine phosphorylation sites of PKC delta in the H(2)O(2)-treated cells were identified as Tyr-311, Tyr-332, and Tyr-512 by mass spectrometric analysis with the use of the precursor-scan method and by immunoblot analysis with the use of phosphorylation site-specific antibodies. Tyr-311 was the predominant modification site among them. In an in vitro study, phosphorylation at this site by Lck, a non-receptor-type tyrosine kinase, enhanced the basal enzymatic activity and elevated its maximal velocity in the presence of diacylglycerol. phosphorylation at Tyr-311 between the regulatory and catalytic domains is a critical step for generation of the active PKC delta in response to H(2)O(2).

9335553	These results indicate that activation of protein kinase c stimulates a kinase which can phosphorylate insulin receptor substrate-1 at serine 612, resulting in an inhibition of insulin signaling in the cell these data suggest that: 1) activation of pkctheta contributes to ikk and jnk activation by ffas;2) ikk and jnk mediate pkctheta signals for irs-1 serine phosphorylation and degradation; ser-302 phosphorylation is dependent on pi 3-kinase/mtor, whereas ser-307 depends on c-jun nh2-terminal kinase to inhibit irs1 tyrosine phosphorylation. Ser-636 is located around the pi 3-kinase binding site and, therefore, thought to inhibit pi 3-kinase signaling.

In vitro labeling of immunoprecipitated proteins from transfected cells showed that ROMK could be phosphorylated by PKA. \| Taken together, these results provide strong evidence that direct phosphorylation of the channel polypeptide by PKA is involved in channel regulation and PKA-dependent phosphorylation is essential for ROMK channel activity.

Inhibitors	bisindolylmaleimide i
Function	Calcium-independent, phospholipid- and diacylglycerol (DAG)-dependent serine/threonine-protein kinase that plays contrasting roles in cell death and cell survival by functioning as a pro-apoptotic protein during DNA damage-induced apoptosis, but acting as an anti-apoptotic protein during cytokine receptor-initiated cell death, is involved in tumor suppression as well as survival of several cancers, is required for oxygen radical production by NADPH oxidase and acts as positive or negative regulator in platelet functional responses. Negatively regulates B cell proliferation and also has an important function in self-antigen induced B cell tolerance induction. Upon DNA damage, activates the promoter of the death-promoting transcription factor BCLAF1/Btf to trigger BCLAF1-mediated p53/TP53 gene transcription and apoptosis. In response to oxidative stress, interact with and activate CHUK/IKKA in the nucleus, causing the phosphorylation of p53/TP53. In the case of ER stress or DNA damage-induced apoptosis, can form a complex with the tyrosine-protein kinase ABL1 which trigger apoptosis independently of p53/TP53. In cytosol can trigger apoptosis by activating MAPK11 or MAPK14, inhibiting AKT1 and decreasing the level of X-linked inhibitor of apoptosis protein (XIAP), whereas in nucleus induces apoptosis via the activation of MAPK8 or MAPK9. Upon ionizing radiation treatment, is required for the activation of the apoptosis regulators BAX and BAK, which trigger the mitochondrial cell death pathway. Can phosphorylate MCL1 and target it for degradation which is sufficient to trigger for BAX activation and apoptosis. Is required for the control of cell cycle progression both at G1/S and G2/M phases. Mediates phorbol 12-myristate 13-acetate (PMA)-induced inhibition of cell cycle progression at G1/S phase by up-regulating the CDK inhibitor CDKN1A/p21 and inhibiting the cyclin CCNA2 promoter activity. In response to UV irradiation can phosphorylate CDK1, which is important for the G2/M DNA damage checkpoint activation. Can protect glioma cells from the apoptosis induced by TNFSF10/TRAIL, probably by inducing increased phosphorylation and subsequent activation of AKT1. Is highly expressed in a number of cancer cells and promotes cell survival and resistance against chemotherapeutic drugs by inducing cyclin D1 (CCND1) and hyperphosphorylation of RB1, and via several pro-survival pathways, including NF-kappa-B, AKT1 and MAPK1/3 (ERK1/2). Can also act as tumor suppressor upon mitogenic stimulation with PMA or TPA. In N-formyl-methionyl-leucyl-phenylalanine (fMLP)-treated cells, is required for NCF1 (p47-phox) phosphorylation and activation of NADPH oxidase activity, and regulates TNF-elicited superoxide anion production in neutrophils, by direct phosphorylation and activation of NCF1 or indirectly through MAPK1/3 (ERK1/2) signaling pathways. May also play a role in the regulation of NADPH oxidase activity in eosinophil after stimulation with IL5, leukotriene B4 or PMA. In collagen-induced platelet aggregation, acts a negative regulator of filopodia formation and actin polymerization by interacting with and negatively regulating VASP phosphorylation. Downstream of PAR1, PAR4 and CD36/GP4 receptors, regulates differentially platelet dense granule secretion; acts as a positive regulator in PAR-mediated granule secretion, whereas it negatively regulates CD36/GP4-mediated granule release. Phosphorylates MUC1 in the C-terminal and regulates the interaction between MUC1 and beta-catenin. The catalytic subunit phosphorylates 14-3-3 proteins (YWHAB, YWHAZ and YWHAH) in a sphingosine-dependent fashion (By similarity). Phosphorylates ELAVL1 in response to angiotensin-2 treatment (PubMed:18285462). Phosphorylates mitochondrial phospolipid scramblase 3 (PLSCR3), resulting in increased cardiolipin expression on the mitochondrial outer membrane which facilitates apoptosis (PubMed:12649167). Phosphorylates SMPD1 which induces SMPD1 secretion (PubMed:17303575).
