Cell division cycle 25B phosphatase (CDC25B)

Target
CDC25B
Molecular classification
Enzyme, Phosphatase, Dual-specificity phosphatase
01

Overview

Cell division cycle 25B phosphatase (CDC25B) is a dual-specificity phosphatase that plays a critical role in cell cycle regulation, particularly in controlling the transition from G2 phase to mitosis (M phase). It activates cyclin-dependent kinase 1 (CDK1, also known as CDC2) by dephosphorylating inhibitory sites, which is essential for mitotic entry. CDC25B exhibits oncogenic properties, and is a considered a potential therapeutic target in cancer treatment strategies aiming to disrupt aberrant cell division.
