Predicted to enable androgen receptor binding activity and nuclear receptor coactivator activity. Predicted to be involved in androgen receptor signaling pathway; positive regulation of transcription by RNA polymerase II; and regulation of proteasomal protein catabolic process. Predicted to act upstream of or within several processes, including Leydig cell differentiation; regulation of gene expression; and spermatid development. Predicted to be located in Golgi apparatus and endoplasmic reticulum. Orthologous to human TMF1 (TATA element modulatory factor 1). [provided by Alliance of Genome Resources, Apr 2022]
