15040786	Cpges-activating protein kinase is ck-ii (casein kinase ii). Mutations of either of two predicted ck-ii phosphorylation sites on cpges (ser113 and ser118) abrogated its phosphorylation and activation both in vitro and in vivo. Hypoxia induced the mitogen-activated protein kinase-mediated phosphorylation of a single serine residue, ser(122), in the protein, and site-directed mutagenesis demonstrated that ser(122) phosphorylation was necessary for hypoxic acceleration of tal1 turnover.

20937870	To identify the regulatory sites of phosphorylation under physiologically relevant conditions, Ca(V)1.1 channels were purified from skeletal muscle and sites of phosphorylation on the α1 subunit were identified by mass spectrometry. Two phosphorylation sites were identified in the proximal C-terminal domain, serine 1575 (S1575) and threonine 1579 (T1579), which are conserved in cardiac Ca(V)1.2 channels (S1700 and T1704, respectively). In vitro phosphorylation revealed that Ca(V)1.1-S1575 is a substrate for both cAMP-dependent protein kinase and calcium/calmodulin-dependent protein kinase II, whereas Ca(V)1.1-T1579 is a substrate for casein kinase 2.

9858576	Mutational analysis and in vitro kinase assays suggested that this 40-kDa Csx/Nkx2.5 kinase is a catalytic subunit of casein kinase II (CKII) that phosphorylates the serine residue between the first and second helix of the homeodomain. This CKII site is phosphorylated in vivo. CKII-dependent phosphorylation of the homeodomain increased Csx/Nkx2. 5 DNA binding. Serine-to-alanine mutation at the CKII phosphorylation site reduced transcriptional activity when the carboxyl-terminal repressor domain was deleted.

Sequencing and phosphoamino acid analysis of tryptic phosphopeptides enabled us to identify Ser178 and Ser199 as the phosphorylation sites of protein kinase A, whereas Thr161 and Ser204 were phosphorylated by protein kinase CK2.

11278496	We now show that human TFIIA is phosphorylated in vivo on serine residues that are partially conserved between yeast and human TFIIA large subunits. Alanine substitution mutation of serine residues 316 and 321 in TFIIA alphabeta reduced TFIIA phosphorylation significantly in vivo. Additional alanine substitutions at serines 280 and 281 reduced phosphorylation to undetectable levels. Mutation of all four serine residues reduced the ability of TFIIA to stimulate transcription in transient transfection assays with various activators and promoters, indicating that TFIIA phosphorylation is required globally for optimal function.

Ap-1 association with vamp4 is enhanced when serine 30 is phosphorylated by casein kinase 2. This phosphorylation-dependent modulation of ap-1 binding is mediated by pacs-1 (phosphofurin acidic cluster sorting protein). Ablation of both the dileucine motif and serine 30 results in a dramatic mislocalization of vamp4 in the regulated secretory pathway.

Quantitative analysis of in vitro phosphorylation demonstrates the presence of two phosphorylation sites for CK-1 and a single site for CK-2. A deletion analysis revealed that the CTF of PS-2 is phosphorylated in vivo within an acidic sequence containing three potential phosphorylation sites for CKs (serines 327, 330, and 335). These data suggest that CK type protein kinases phosphorylate the CTF of PS-2 within its hydrophilic loop domain in vivo. Interestingly, the potential phosphorylation sites are located directly adjacent to the recently identified caspase cleavage sites.

10448092	Site-specific mutagenesis of maz revealed that the serine residue at position 480 was the major site of phosphorylation by ckii both in vitro and in vivo. Phosphorylation of maz by ckii at this serine residue was required for maximum binding of maz to the pyrimidine-rich dna of the nuclease-hypersensitive element (nhe) in the 5'-end promoter region of the c-myc gene. Mutation of serine at position 480 to alanine eliminated the dna-binding activity of maz to this element.

Using point mutants of C/EBPδ the major phosphorylation site for CK2 was mapped to serine 57, which is located within the transactivation domain of C/EBPδ. For proper functioning as a transcription factor C/EBPδ has to be translocated into the nucleus where it forms heterodimers with other members of the C/EBP family of proteins and ATF4. Here, we found that CK2 phosphorylation does neither influence the subcellular localization of C/EBPδ nor its interaction with C/EBPβ, but rather does CK2 phosphorylation modulate the transcriptional activity of C/EBPδ.

Moreover, phosphorylation of serine 129 was reduced in vivo upon inhibition of ck-1 or ck-2.
