Myb Gene Summary [Mouse]
Enables DNA-binding transcription activator activity, RNA polymerase II-specific; RNA polymerase II cis-regulatory region sequence-specific DNA binding activity; and WD40-repeat domain binding activity. Involved in positive regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including cellular response to cytokine stimulus; hematopoietic or lymphoid organ development; and hemopoiesis. Located in cytosol and nucleus. Part of RNA polymerase II transcription regulator complex. Is expressed in several structures, including alimentary system; brain; genitourinary system; limb; and sensory organ. Used to study essential thrombocythemia and myelofibrosis. Orthologous to human MYB (MYB proto-oncogene, transcription factor). [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 Myb often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
