Cyclin-dependent kinase inhibitor 1C (p57, Kip2), also known as CDKN1C, is protein which in humans is encoded by the CDKN1C imprinted gene.[2]

Function

Cyclin-dependent kinase inhibitor 1C is a tight-binding inhibitor of several G1 cyclin/Cdk complexes and a negative regulator of cell proliferation. Mutations of CDKN1C are implicated in sporadic cancers and Beckwith-Wiedemann syndrome suggesting that it is a tumor suppressor candidate.[2]

CDKN1C 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.[3] Thus p57KIP2 causes arrest of the cell cycle in G1 phase.

Clinical significance

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.[4] Loss-of-function mutations in this gene have also been shown associated to the IMAGe syndrome (Intrauterine growth restriction, Metaphyseal dysplasia, Adrenal hypoplasia congenita, and Genital anomalies).[5] Loss of p57 function is also implicated in complete hydatidiform moles.[6]

Interactions

Cyclin-dependent kinase inhibitor 1C has been shown to interact with:
