Pnp Gene Summary [Rat]

Enables purine-nucleoside phosphorylase activity. Predicted to be involved in several processes, including allantoin metabolic process; nucleobase-containing small molecule metabolic process; and positive regulation of interleukin-2 production. Predicted to act upstream of or within inosine catabolic process; positive regulation of T cell activation; and urate biosynthetic process. Located in extracellular region. Human ortholog(s) of this gene implicated in purine nucleoside phosphorylase deficiency and purine-pyrimidine metabolic disorder. Orthologous to human PNP (purine nucleoside phosphorylase).

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 Pnp often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
