Inhibition of CK1α stabilizes ATM, resulting in the restoration of DSB signaling, and thus increases ENZA-induced cell death and growth arrest.

Moreover, phosphorylation of serine 129 was reduced in vivo upon inhibition of ck-1 or ck-2.\| together, these data may indicate that ck-1 and ck-2 are involved in the regulation of neuronal function and one may speculate that phosphorylation of alpha-synuclein could affect its binding to membranes.

9045708	Purified CKI and CKII phosphorylate the wild-type carboxyl terminus of VMAT2, but not a double mutant with both serines 512 and 514 replaced by alanine. The protein kinase inhibitor CKI-7 and unlabeled GTP both block in vitro phosphorylation by cell homogenates, indicating a role for CKII and possibly CKI in vivo. Both kinases phosphorylate the VMAT2 fusion protein to a much greater extent than a similar fusion protein containing the carboxyl terminus of VMAT1, consistent with differential phosphorylation of the two transporters observed in intact cells.

10617630	In vitro experiments and two-dimensional phosphopeptide mapping provided further evidence that serine 129 was phosphorylated by ck-1 and ck-2. Moreover, phosphorylation of serine 129 was reduced in vivo upon inhibition of ck-1 or ck-2. These data demonstrate that alpha-synuclein is constitutively phosphorylated within its c terminus and may indicate that the function of alpha-synuclein is regulated by phosphorylation/dephosphorylation.From these data we conclude that _-synuclein is predominantly phosphorylated at serine residue 129. However, a second serine at position 87 is also used for phosphorylation to some extent. together, these data may indicate that ck-1 and ck-2 are involved in the regulation of neuronal function and one may speculate that phosphorylation of _-synuclein could affect its binding to membranes.

Function	Casein kinases are operationally defined by their preferential utilization of acidic proteins such as caseins as substrates. It can phosphorylate a large number of proteins. Participates in Wnt signaling. Phosphorylates CTNNB1 at 'Ser-45'. May phosphorylate PER1 and PER2. May play a role in segregating chromosomes during mitosis (PubMed:11955436, PubMed:1409656, PubMed:18305108). May play a role in keratin cytoskeleton disassembly and thereby, it may regulate epithelial cell migration (PubMed:23902688).
