Jun Gene Summary [Mouse]
Enables chromatin binding activity and transcription cis-regulatory region binding activity. Involved in cellular response to anisomycin and positive regulation of transcription by RNA polymerase II. Acts upstream of or within several processes, including circulatory system development; eyelid development in camera-type eye; and positive regulation of cell population proliferation. Located in nucleus. Part of transcription factor AP-1 complex and transcription repressor complex. Is expressed in several structures, including alimentary system; central nervous system; genitourinary system; long bone; and sensory organ. Used to study psoriasis and pulmonary emphysema. Human ortholog(s) of this gene implicated in pulmonary tuberculosis. Orthologous to human JUN (Jun proto-oncogene, AP-1 transcription factor subunit).

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