靶标信息
Constitutively active protein kinase that acts as a negative regulator in the hormonal control of glucose homeostasis, Wnt signaling and regulation of transcription factors and microtubules, by phosphorylating and inactivating glycogen synthase (GYS1 or GYS2), EIF2B, CTNNB1/beta-catenin, APC, AXIN1, DPYSL2/CRMP2, JUN, NFATC1/NFATC, MAPT/TAU and MACF1 (PubMed:1846781, PubMed:9072970, PubMed:14690523, PubMed:20937854, PubMed:12554650, PubMed:11430833, PubMed:16484495).
Requires primed phosphorylation of the majority of its substrates (PubMed:11430833, PubMed:16484495).
In skeletal muscle, contributes to insulin regulation of glycogen synthesis by phosphorylating and inhibiting GYS1 activity and hence glycogen synthesis (PubMed:8397507).
