The protein encoded by this gene belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance throughout the cell cycle. Cyclins function as regulators of CDKs (Cyclin-dependent kinase). Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mit… WebMar 21, 2024 · Cyclin D1 controls development of cerebellar granule cell progenitors through phosphorylation and stabilization of ATOH1.

WebResults of the western blot analysis and qPCR revealed that ALO increased the protein and mRNA of Bax and decreased Bcl-2 via the mitochondrial death pathway. In addition, ALO induced cell cycle arrest at the G2/M phase with a concomitant increase in p21 and p53 and a decrease in cyclin D1 and B1. WebThe G2/M transition is under the control of cyclin A/B-CDK1. The late G2 checkpoint corresponds to a long G2 delay and concerns cells that have been irradiated in G1 or S phase. ATR, rather than ATM, phosphorylates CHK1 that then phosphorylates and inhibits the phosphatases CDC25A/CDC25C, leading to CDK1 phosphorylation and cell cycle …
WebOct 1, 1999 · Genes encoding D-type cyclins (D1, D2, and D3) are progressively induced as a part of the response to mitogenic stimulation. The mechanisms of D-type cyclin expression are poorly understood.
