Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables cyclin binding activity and cyclin-dependent protein serine/threonine kinase activity. Acts upstream of or within several processes, including cellular response to interleukin-4; cellular response to lipid; and regulation of type B pancreatic cell proliferation. Located in bicellular tight junction and nucleus. Part of cyclin D1-CDK4 complex; cyclin D2-CDK4 complex; and transcription regulator complex. Is expressed in several structures, including alimentary system; branchial arch; nervous system; sensory organ; and urinary system. Used to study skin melanoma and type 1 diabetes mellitus. Human ortholog(s) of this gene implicated in several diseases, including carcinoma (multiple); familial melanoma; glioblastoma; obesity; and type 2 diabetes mellitus. Orthologous to human CDK4 (cyclin dependent kinase 4).
