GenAge entry for CDKN2B (Homo sapiens)

Gene name (HAGRID: 288)

HGNC symbol: CDKN2B
Aliases: P15; MTS2; INK4B; TP15; CDK4I; p15INK4b
Common name: cyclin-dependent kinase inhibitor 2B (p15, inhibits CDK4)

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence directly linking the gene product to ageing in a cellular model system
Description: The p15 tumor suppressor (CDKN2B) is located in the same region as p16 (CDKN2A), and is also involved in cell cycle, senescence and cancer. This region is frequently mutated and/or deleted in a wide variety of tumors [2229]. Genetic variants have been identified close to both p15 and p16 in patients with type 2 diabetes and cardiovascular disease [2230]. Although CDKN2B seems to have a role in cellular senescence and age-related diseases, its implication in broader aspects of ageing is still unknown.
