GenAge entry for PTPN1 (Homo sapiens)

Gene name (HAGRID: 33)

HGNC symbol: PTPN1
Aliases: PTP1B
Common name: protein tyrosine phosphatase, non-receptor type 1

Potential relevance to the human ageing process

Main reason for selection: Entry selected based on evidence showing that the gene product to be a target of genes previously linked to ageing
Description: PTPN1 inhibits insulin (INS) signalling and plays a role in INS sensitivity and fuel metabolism. Mice lacking PTPN1 are protected from diet-induced obesity and have enhanced enhanced INS sensitivity [323]. PTP1B negatively regulates leptin (LEP) signalling [1912]. PTPN1 may thus be related to certain age-associated pathologies such as obesity.
