SUBCELLULAR LOCALIZATION	plasma membrane,junction,tight

	intracellular,cytoplasm,cytosolic
	intracellular,nucleus,chromatin/chromosome
	intracellular,nucleus,nucleolus

basic FUNCTION	serine/threonine kinase, involved in cell cycle regulation (G1 to S transition)
	essential for the G1- to S-phase transition during the cell cycle and its expression is primarily controlled at the transcriptional level
	key regulator of the transition through the G(1) phase of the cell cycle
	controls beta-cell mass by recruiting quiescent cells to enter the cell cycle
	plays a previously unrecognized role in thymocyte maturation and adhesion, but is not required for thymocyte proliferation and is not required for lymphocyte trafficking to the lung following allergen sensitization and challenge ((
	CCND1-CDK4 axis is not only critical in glial tumor cells but also in stromal-derived cells in the surrounding tumor microenvironment that are vital to sustain tumor outgrowth

CELLULAR PROCESS	cell cycle, progression
	nucleotide, repair

PHYSIOLOGICAL PROCESS

text	negative control

PATHWAY

metabolism

signaling

a component	complexing with cyclins D (D1, D2, D3)
	cyclin D2 and CDK4 formed a complex in the cytoplasm and approached the nucleus
	CDK2/CDK4/NPM pathway is a major guardian of centrosome dysfunction and genomic integrity
	CCND1-CDK4 axis is not only critical in glial tumor cells but also in stromal-derived cells in the surrounding tumor microenvironment that are vital to sustain tumor outgrowth

INTERACTION

DNA

RNA

small molecule

protein	target by MYC phosphorylating and blocking active repression by RB1
	ZNF655
	bound to cyclin D1 and has a phosphorylated T-loop, but is in an inactive conformation
	YY1 inhibited CDKN1A complex formation with CDK4 and CCND1
	UCHL1 physically interacts with CDK1, CDK4, and CDK5, enhancing their kinase activity
	novel function of CCND1 in promoting cell cycle progression by enhancing STK38/STK38L kinase activity independent of CDK4
	RUNX1T1 controls proliferation and the neurotoxic effect of microglia by epigenetically regulating CDK4 and LAT2 via its interaction with HDACs
	CIAPIN1 played an important role in the proliferation of liver cancer cells through increasing the expressions of cell cycle related proteins CCND1, CDK2, CDK4, and CCNE1
	SHCBP1 promoted cell cycle progression by regulating the CDK4&

REGULATION

inhibited by

PPP3CA (inhibits the kinase activity of CDK4 by preventing its reassociation into an active kinase complex by utilizing common association domains used by cyclin D and CDKN2A)

repressed by

JUND (increased JunD in polyamine-deficient cells was associated with a significant inhibition of CDK4 transcription, as indicated by repression of CDK4-promoter activity and decreased levels of CDK4 mRNA and protein)
