Ptpn2 Gene Summary [Rat]
Enables non-membrane spanning protein tyrosine phosphatase activity. Predicted to be involved in several processes, including hemopoiesis; negative regulation of leukocyte differentiation; and regulation of signal transduction. Predicted to act upstream of or within negative regulation of transcription by RNA polymerase II and protein dephosphorylation. Predicted to be located in several cellular components, including endoplasmic reticulum; endoplasmic reticulum-Golgi intermediate compartment; and nucleoplasm. Predicted to be active in endosome lumen and nucleus. Orthologous to human PTPN2 (protein tyrosine phosphatase non-receptor type 2). [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 Ptpn2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
