Overview

Cyclin-dependent kinase 3 (CDK3) is a serine/threonine protein kinase that plays a role in cell cycle control, particularly at the G0-G1 and G1-S transitions. It requires interaction with cyclins for activation and can phosphorylate histone H1. Recent studies suggest it may have oncogenic properties and be involved in cancer progression. While it's a potential therapeutic target, current inhibitors primarily focus on other CDK family members.
