Sh3pxd2b Gene Summary [Mouse]
Enables SH2 domain binding activity and phosphatidylinositol phosphate binding activity. Involved in several processes, including osteoblast fate commitment; podosome assembly; and skeletal system development. Located in cytoplasm and podosome. Is expressed in several structures, including branchial arch; central nervous system; heart; jaw; and skeleton. Used to study glaucoma and otitis media. Human ortholog(s) of this gene implicated in Frank-Ter Haar syndrome. Orthologous to human SH3PXD2B (SH3 and PX domains 2B). [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 Sh3pxd2b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
