GSK3B Summary & Protein Information

GSK3B Background

Catalytic activity: ATP + [tau protein] = ADP + [tau protein] phosphate.; ATP + a protein = ADP + a phosphoprotein.
Enzyme regulation: ENZYME REGULATION: Activated by phosphorylation at Tyr-216. In response to insulin, inhibited by phosphorylation at Ser-9 by PKB/AKT1 and RPS6KA3; phosphorylation at this site causes a conformational change, preventing access of substrates to the active site. Inhibited by lithium. {ECO:0000269|PubMed:11749387, ECO:0000269|PubMed:12554650, ECO:0000269|PubMed:19366350, ECO:0000269|PubMed:8524413}.
Subunit structure: Monomer. Interacts with ARRB2, DISC1 and ZBED3 (By similarity). Interacts with CABYR, MMP2, MUC1, NIN and PRUNE Interacts with AXIN1; the interaction mediates hyperphosphorylation of CTNNB1 leading to its ubiquitination and destruction. Interacts with and phosphorylates SNAI1. Interacts with DNM1L (via a C-terminal domain). Found in a complex composed of MACF1, APC, AXIN1, CTNNB1 and GSK3B (By similarity). Interacts with SGK3. Interacts with DAB2IP (via C2 domain); the interaction stimulates GSK3B kinase activation. Interacts (via C2 domain) with PPP2CA. Interacts with the CLOCK-ARNTL/BMAL1 heterodimer. Interacts with the ARNTL/BMAL1. {ECO:0000250, ECO:0000269|PubMed:11004522, ECO:0000269|PubMed:12054501, ECO:0000269|PubMed:12554650, ECO:0000269|PubMed:15448698, ECO:0000269|PubMed:15647282, ECO:0000269|PubMed:15752768, ECO:0000269|PubMed:16428445, ECO:0000269|PubMed:17318175, ECO:0000269|PubMed:19493954, ECO:0000269|PubMed:19946213, ECO:0000269|PubMed:20080667, ECO:0000269|PubMed:9731200, ECO:0000269|PubMed:9819408}.
Subcellular location: Cytoplasm. Nucleus. Cell membrane. Note=The phosphorylated form shows localization to cytoplasm and cell membrane. The MEMO1-RHOA-DIAPH1 signaling pathway controls localization of the phosphorylated form to the cell membrane.
Tissue specificity: Expressed in testis, thymus, prostate and ovary and weakly expressed in lung, brain and kidney. Colocalizes with EIF2AK2/PKR and TAU in the Alzheimer disease (AD) brain. {ECO:0000269|PubMed:21029237}.
Post-translational: Phosphorylated by AKT1 and ILK1. Upon insulin-mediated signaling, the activated PKB/AKT1 protein kinase phosphorylates and desactivates GSK3B, resulting in the dephosphorylation and activation of GYS1. Activated by phosphorylation at Tyr-216. {ECO:0000269|PubMed:12054501, ECO:0000269|PubMed:12554650, ECO:0000269|PubMed:16484495, ECO:0000269|PubMed:20937854, ECO:0000269|PubMed:21029237, ECO:0000269|PubMed:8250835}.; Mono-ADP-ribosylation by PARP10 negatively regulates kinase activity.
Sequence similarity: Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family. GSK-3 subfamily. {ECO:0000305}.; Contains 1 protein kinase domain. {ECO:0000255|PROSITE-ProRule:PRU00159}.
General information above from UniProt

GSK3B is a serine-threonine kinase, belonging to the glycogen synthase kinase subfamily. It Contains 1 protein kinase domain, and is expressed in testis, thymus, prostate and ovary and weakly expressed in lung, brain and kidney. GSK3B is involved in energy metabolism, neuronal cell development, and body pattern formation. Polymorphisms in GSK3B gene have been implicated in modifying risk of Parkinson disease, and studies in mice show that overexpression of this gene may be relevant to the pathogenesis of Alzheimer disease. GSK3B participates in the Wnt signaling pathway. It is implicated in the hormonal control of several regulatory proteins including glycogen synthase, MYB and the transcription factor JUN. Phosphorylates JUN at sites proximal to its DNA-binding domain, thereby reducing its affinity for DNA. Phosphorylates MUC1 in breast cancer cells, and decreases the interaction of MUC1 with CTNNB1/beta-catenin. GSK3B also plays an important role in ERBB2-dependent stabilization of microtubules at the cell cortex. It prevents the phosphorylation of APC and CLASP2, allowing its association with the cell membrane. In turn, membrane-bound APC allows the localization of MACF1 to the cell membrane, which is required for microtubule capture and stabilization. GSK3B phosphorylates MACF1 and this phosphorylation inhibits the binding of MACF1 to microtubules which is critical for its role in bulge stem cell migration and skin wound repair. It may be required for early embryo development and neuron differentiation.
