Target intelligence / Profile preview

Cyclin-dependent kinase 1 regulatory subunit 2 (CCNB1)

Target
CCNB1
Molecular classification
Cyclin, Regulatory Protein
01

Overview

Cyclin B1 (CCNB1) is a regulatory protein essential for controlling the cell cycle at the G2/M transition. It forms a complex with cyclin-dependent kinase 1 (CDK1), creating the maturation-promoting factor (MPF), which is crucial for initiating mitosis. Overexpression of CCNB1 is observed in various cancers and associated with aggressive tumor behavior and poor clinical outcomes, making it a potential therapeutic target.
