Automated description from the Alliance of Genome Resources (Release 3.1.1)
Predicted to have several functions, including ATPase binding activity; phosphotyrosine residue binding activity; and sodium channel regulator activity. Predicted to be involved in several processes, including negative regulation of membrane protein ectodomain proteolysis; regulation of membrane depolarization during action potential; and regulation of sodium ion transmembrane transporter activity. Predicted to localize to cytoplasm and cytoplasmic side of plasma membrane. Is expressed in several structures, including alimentary system; cranial ganglion; nasal epithelium; urinary system; and vibrissa. Orthologous to human PTPN3 (protein tyrosine phosphatase non-receptor type 3).
