Ptpn1 Gene Summary [Rat]
Enables insulin receptor binding activity; protein phosphatase 2A binding activity; and protein tyrosine phosphatase activity. Involved in several processes, including cellular response to peptide hormone stimulus; positive regulation of apoptotic process; and regulation of protein metabolic process. Located in mitochondrial crista and mitochondrial matrix. Is active in glutamatergic synapse and postsynapse. Biomarker of hyperinsulinism and hypertension. Human ortholog(s) of this gene implicated in coronary artery disease; essential hypertension; and type 2 diabetes mellitus. Orthologous to human PTPN1 (protein tyrosine phosphatase non-receptor type 1). [provided by Alliance of Genome Resources, Jul 2025]

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Ptpn1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
