P57 (gene)
Introduction
Overview
Overview
p57 or p57KIP2 is a tumor suppressor human gene on chromosome 11 (11p15) and belongs to the cip/kip gene family. It encodes a cell cycle inhibitor that binds to G1 cyclin-CDK complexes. [1] Thus p57KIP2 causes arrest of the cell cycle in G1 phase. A mutation of this gene may lead to loss of control over the cell cycle leading to uncontrolled cellular proliferation. p57KIP2 has been associated with Beckwith-Wiedemann syndrome (BWS) which is characterized by increased risk of tumor formation in childhood.
