Foxa1 Gene Summary [Mouse]
Enables DNA-binding transcription factor activity; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and chromatin binding activity. Involved in chromatin remodeling. Acts upstream of or within several processes, including lung development; prostate gland development; and regulation of transcription by RNA polymerase II. Located in microvillus and nucleus. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; respiratory system; and sensory organ. Human ortholog(s) of this gene implicated in breast cancer; gastrointestinal system cancer (multiple); and lung cancer (multiple). Orthologous to human FOXA1 (forkhead box A1).

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 Foxa1 often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
