Smarcb1 Gene Summary [Mouse]
Predicted to enable several functions, including Tat protein binding activity; p53 binding activity; and transcription coactivator activity. Acts upstream of or within blastocyst hatching; hepatocyte differentiation; and negative regulation of cell population proliferation. Located in XY body and germ cell nucleus. Part of SWI/SNF complex; nBAF complex; and npBAF complex. Is expressed in several structures, including branchial arch; central nervous system; genitourinary system; limb primordium; and sensory organ. Used to study atypical teratoid rhabdoid tumor. Human ortholog(s) of this gene implicated in Coffin-Siris syndrome 3; meningioma; rhabdoid cancer; rhabdoid tumor predisposition syndrome 1; and schwannomatosis (multiple). Orthologous to human SMARCB1 (SWI/SNF related BAF chromatin remodeling complex subunit B1). [provided by Alliance of Genome Resources, Apr 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 Smarcb1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
