Paxbp1 Gene Summary [Mouse]
Enables histone methyltransferase binding activity. Acts upstream of or within positive regulation of myoblast proliferation; positive regulation of transcription by RNA polymerase II; and regulation of skeletal muscle satellite cell proliferation. Located in nucleus. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Orthologous to human PAXBP1 (PAX3 and PAX7 binding protein 1). [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 Paxbp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- enzyme binding
- transcription factor binding
- GC-rich sequence DNA-binding factor-like protein
