Ptprs Gene Summary [Rat]
Enables protein tyrosine phosphatase activity. Involved in presynapse assembly; regulation of postsynaptic density assembly; and synaptic membrane adhesion. Located in postsynaptic density membrane and synaptic vesicle membrane. Is active in glutamatergic synapse and presynaptic membrane. Orthologous to human PTPRS (protein tyrosine phosphatase receptor type S). [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 Ptprs often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
