Ptpn22 Gene Summary [Mouse]

Enables SH3 domain binding activity; kinase binding activity; and protein tyrosine phosphatase activity. Involved in several processes, including dephosphorylation; regulation of cytokine production; and regulation of intracellular signal transduction. Acts upstream of or within T cell differentiation and T cell receptor signaling pathway. Located in cytoplasm; cytoplasmic side of plasma membrane; and nucleus. Is expressed in dorsal root ganglion; peripheral nervous system; and thymus primordium. Human ortholog(s) of this gene implicated in several diseases, including Addison's disease; Meniere's disease; autoimmune disease (multiple); graft-versus-host disease; and pulmonary tuberculosis. Orthologous to human PTPN22 (protein tyrosine phosphatase non-receptor type 22). [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 mouse Ptpn22 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
