Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables several functions, including DNA-binding transcription repressor activity, RNA polymerase II-specific; cAMP response element binding activity; and protein dimerization activity. Acts upstream of or within with a negative effect on regulation of transcription by RNA polymerase II. Acts upstream of or within chromatin remodeling; negative regulation of fat cell differentiation; and negative regulation of transcription by RNA polymerase II. Located in nucleus. Is expressed in several structures, including blood island; central nervous system; genitourinary system; musculoskeletal system; and neural retina. Orthologous to human JDP2 (Jun dimerization protein 2).
