disease:Defects in CDKN2B are involved in tumor formation.,function:Interacts strongly with CDK4 and CDK6. Potent inhibitor. Potential effector of TGF-beta induced cell cycle arrest.,polymorphism:Genetic variations in CDKN2B may underlie susceptibility to uveal melanoma [MIM:155720]. Uveal melanoma is the most common type of ocular malignant tumor, consisting of overgrowth of uveal melanocytes and often preceded by a uveal nevus.,similarity:Belongs to the CDKN2 cyclin-dependent kinase inhibitor family.,similarity:Contains 4 ANK repeats.,subunit:Heterodimer of CDKN2B with CDK4 or CDK6.,
Cytoplasm . Also found in the nucleus.
