Human Gene ID：595

The protein encoded by this gene belongs to the highly conserved cyclin family, whose members are characterized by a dramatic periodicity in protein abundance throughout the cell cycle. Cyclins function as regulators of CDK kinases. Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. This cyclin forms a complex with and functions as a regulatory subunit of CDK4 or CDK6, whose activity is required for cell cycle G1/S transition. This protein has been shown to interact with tumor suppressor protein Rb and the expression of this gene is regulated positively by Rb. Mutations, amplification and overexpression of this gene, which alters cell cycle progression, are observed frequently in a variety of tumors and may contribute to tumorigenesis.

Function：Regulatory component of the cyclin D1-CDK4 (DC) complexthat phosphorylates and inhibits members of the retinoblastoma (RB)protein family including RB1 and regulates the cell-cycle duringG(1)/S transition. Phosphorylation of RB1 allows dissociation ofthe t
Subunit：Interacts with FBXO4. Interacts witheither CDK4 or CDK6 protein kinase to form a serine/threoninekinase holoenzyme complex. The cyclin subunit imparts substratespecificity to the complex. Component of the ternary complexCCND1/CDK4/CDKN1B required for nucl
Subcellular Location：Nucleus. Cytoplasm. Membrane. Note=CyclinD-CDK4 complexes accumulate at the nuclear membrane and are thentranslocated to the nucleus through interaction with KIP/CIP familymembers.
Post-translational modifications：Phosphorylation at Thr-286 by MAP kinases is required forubiquitination and degradation following DNA damage. It probablyplays an essential role for recognition by the FBXO31 component ofSCF (SKP1-cullin-F-box) protein ligase complex.
Ubiquitinated, p
DISEASE：Note=A chromosomal aberration involving CCND1 may be acause of B-lymphocytic malignancy, particularly mantle-celllymphoma (MCL). Translocation t(11;14)(q13;q32) with immunoglobulingene regions. Activation of CCND1 may be oncogenic by directlyaltering prog
Similarity：Belongs to the cyclin family. Cyclin D subfamily.
