Sin3b Gene Summary [Mouse]
Enables chromatin binding activity and transcription corepressor activity. Involved in cardiac muscle tissue development; negative regulation of DNA-templated transcription; and skeletal muscle tissue development. Located in several cellular components, including autosome; nucleus; and sex chromosome. Is expressed in several structures, including central nervous system; dorsal root ganglion; eye; genitourinary system; and paraxial mesenchyme. Orthologous to human SIN3B (SIN3 transcription regulator family member B). [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 Sin3b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
