Summaries for CDKN2C Gene

Entrez Gene Summary for CDKN2C Gene

  • The protein encoded by this gene is a member of the INK4 family of cyclin-dependent kinase inhibitors. This protein has been shown to interact with CDK4 or CDK6, and prevent the activation of the CDK kinases, thus function as a cell growth regulator that controls cell cycle G1 progression. Ectopic expression of this gene was shown to suppress the growth of human cells in a manner that appears to correlate with the presence of a wild-type RB1 function. Studies in the knockout mice suggested the roles of this gene in regulating spermatogenesis, as well as in suppressing tumorigenesis. Two alternatively spliced transcript variants of this gene, which encode an identical protein, have been reported. [provided by RefSeq, Jul 2008]

GeneCards Summary for CDKN2C Gene

CDKN2C (Cyclin-Dependent Kinase Inhibitor 2C) is a Protein Coding gene. Diseases associated with CDKN2C include Multiple Endocrine Neoplasia 1 and Choriocarcinoma Of The Testis. Among its related pathways are HTLV-I infection and ERK Signaling. GO annotations related to this gene include protein kinase binding and cyclin-dependent protein serine/threonine kinase inhibitor activity. An important paralog of this gene is CDKN2B.

UniProtKB/Swiss-Prot for CDKN2C Gene

  • Interacts strongly with CDK6, weakly with CDK4. Inhibits cell growth and proliferation with a correlated dependence on endogenous retinoblastoma protein RB.
