General description

Cyclin-dependent kinase 4 inhibitor B (UniProt: P55271; also known as p14-INK4b, p15-INK4b) is encoded by the Cdkn2b gene (Gene ID: 12579) in murine species. p15-INK4b is a ubiquitously expressed member of the INK4 family of cyclin-dependent kinase inhibitors. It induces a G1-phase cell cycle arrest through heterodimerization with cyclin-dependent kinase 4/6, thereby serves as a tumor suppressor. It also serves as a potential effector of TGF-beta induced cell cycle arrest. p15 also plays an important role in the regulation of cellular commitment of hematopoietic progenitor cells and myeloid cell differentiation. It contains four ankyrin repeats (aa 5-34; 38-66; 71-100; and 104-130). p15 shares extensive homology with p16 and serves an important backup function for p16 in senescence. Cdkn2b gene is frequently hypermethylated in myeloid neoplasia. Genes coding for both p15 and p16 are reported to often deleted in human tumors. p15 can serve as a good prognostic marker for monitoring the response to treatment with DNA methylation inhibitors.
