Bcl11b Gene Summary [Mouse]
Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including T cell differentiation; epithelial cell development; and neuron differentiation. Located in neuron projection and nucleus. Part of SWI/SNF complex. Is expressed in several structures, including alimentary system; central nervous system; cranium; nose; and skin. Human ortholog(s) of this gene implicated in immunodeficiency 49. Orthologous to human BCL11B (BCL11 transcription factor 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 Bcl11b often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
