Pbx2 Gene Summary [Mouse]
Enables chromatin binding activity. Acts upstream of or within embryonic limb morphogenesis; positive regulation of transcription by RNA polymerase II; and proximal/distal pattern formation. Located in nucleus. Part of transcription regulator complex. Is expressed in several structures, including alimentary system; central nervous system; embryo mesenchyme; eye; and genitourinary system. Orthologous to human PBX2 (PBX homeobox 2). [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 Pbx2 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
