Phosphatase cdc25
WebNov 8, 2004 · Abstract. Cdc25B is a phosphatase that catalyzes the dephosphorylation and activation of the cyclin-dependent kinases, thus driving cell cycle progression. We have identified two residues, R488 and Y497, located >20 Å from the active site, that mediate protein substrate recognition without affecting activity toward small-molecule substrates. WebJan 30, 2009 · The protein Tyr phosphatase (PTP) superfamily is distinguished by its CX 5 R catalytic signature motif shared by all of its members. It consists of the classical PTPs, the dual-specificity phosphatases (DSPs), the Cdc25 type phosphatases, and the low-molecular-weight phosphatases.

WebThis active phosphatase dephosphorylates Thr138 and holds Cdc25 in an inactive state until replication has been successfully completed and/or any DNA damage has been repaired. At this point, Chk1 activity wanes and dephosphorylation of Thr138 by PP2A/B56δ diminishes, allowing constitutive Cdk2 activity to predominate and phospho-T138 to ... WebCDC25B is a member of the CDC25 family of phosphatases. CDC25B activates the cyclin dependent kinase CDC2 by removing two phosphate groups and it is required for entry …
