Xirp1 Gene Summary [Mouse]
Predicted to enable actin filament binding activity and filamin binding activity. Involved in myoblast differentiation involved in skeletal muscle regeneration; protein localization; and satellite cell activation involved in skeletal muscle regeneration. Acts upstream of or within several processes, including Notch signaling pathway; negative regulation of cell population proliferation; and striated muscle cell development. Located in adherens junction and fascia adherens. Is expressed in several structures, including heart; musculature; and tail somite. Used to study hypertrophic cardiomyopathy. Orthologous to human XIRP1 (xin actin binding repeat containing 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 Xirp1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
