Predicted to enable AF-2 domain binding activity; estrogen receptor binding activity; and nuclear receptor coactivator activity. Involved in several processes, including bone trabecula formation; positive regulation of phosphate metabolic process; and regulation of transcription, DNA-templated. Predicted to be located in cytosol and nucleoplasm. Predicted to be part of mediator complex. Predicted to be active in nucleus. Is expressed in brown fat; central nervous system; heart; and sensory organ. Human ortholog(s) of this gene implicated in obesity. Orthologous to human PPARGC1B (PPARG coactivator 1 beta).
