Automated description from the Alliance of Genome Resources (Release 7.1.0)
Enables DNA-binding transcription activator activity, RNA polymerase II-specific; E-box binding activity; and protein heterodimerization activity. Involved in several processes, including negative regulation of cold-induced thermogenesis; positive regulation of brown fat cell differentiation; and positive regulation of transcription by RNA polymerase II. Acts upstream of or within regulation of osteoclast differentiation. Located in cytosol and nucleus. Is expressed in several structures, including adipose tissue; branchial arch; early conceptus; genitourinary system; and gut. Human ortholog(s) of this gene implicated in renal cell carcinoma. Orthologous to human TFE3 (transcription factor binding to IGHM enhancer 3).
