Biological function summary
GWL influences the cell cycle and mitotic progression by modulating the activity of the phosphatase inhibitor proteins ENSA and ARPP19. It is part of a functional complex with these proteins when activated leading to the inhibition of Protein Phosphatase 2A (PP2A) during mitosis which allows for proper chromosome condensation and segregation. This ensures that the cells divide accurately maintaining genomic stability.
Pathways
Different cellular pathways integrate their signals through GWL to regulate mitosis. One of the key pathways is the cell cycle control pathway where GWL works alongside CDK1 and is essential for the phosphorylation cascade that leads to mitotic entry. Another pathway of note is the mitotic spindle assembly checkpoint where GWL interacts with proteins such as BUB1 and MAD2 helping establish mechanisms that ensure cells do not prematurely progress through mitosis with errors.
일반 정보
기능
Serine/threonine kinase that plays a key role in M phase by acting as a regulator of mitosis entry and maintenance (PubMed : 19680222). Acts by promoting the inactivation of protein phosphatase 2A (PP2A) during M phase : does not directly inhibit PP2A but acts by mediating phosphorylation and subsequent activation of ARPP19 and ENSA at 'Ser-62' and 'Ser-67', respectively (PubMed : 38123684). ARPP19 and ENSA are phosphatase inhibitors that specifically inhibit the PPP2R2D (PR55-delta) subunit of PP2A. Inactivation of PP2A during M phase is essential to keep cyclin-B1-CDK1 activity high (PubMed : 20818157). Following DNA damage, it is also involved in checkpoint recovery by being inhibited. Phosphorylates histone protein in vitro; however such activity is unsure in vivo. May be involved in megakaryocyte differentiation.
서열 유사성
Belongs to the protein kinase superfamily. AGC Ser/Thr protein kinase family.
Post-translational modifications
Phosphorylation at Thr-741 by CDK1 during M phase activates its kinase activity (By similarity). Maximum phosphorylation occurs in prometaphase.
