GenAge entry for PIK3CB (Homo sapiens)

Gene name (HAGRID: 36)

HGNC symbol: PIK3CB
Aliases: PIK3C1
Common name: phosphatidylinositol-4,5-bisphosphate 3-kinase, catalytic subunit beta

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 non-mammalian animal model
Description: PIK3CB is involved in the signal transduction of insulin (INS) and insulin-like pathways including the activation of the MAPK pathway [154]. A homologue of PIK3CB, age-1, has been related to ageing in roundworms [1518]. Genotype combinations in the human PIK3CB and IGF1R genes have been related to plasma IGF1 levels and longevity [141], though the elucidation of PIK3CB's role in ageing will require more detailed studies.
