Mafa 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. Involved in positive regulation of transcription by RNA polymerase II. Acts upstream of or within positive regulation of DNA-templated transcription. Located in nucleus. Is expressed in several structures, including lens vesicle; myotome; nervous system; pancreas; and spleen. Used to study maturity-onset diabetes of the young and type 2 diabetes mellitus. Orthologous to human MAFA (MAF bZIP transcription factor A). [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 Mafa often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
