Predicted to enable nuclear receptor binding activity and nuclear receptor coactivator activity. Predicted to be involved in mRNA splicing, via spliceosome and positive regulation of androgen receptor activity. Predicted to act upstream of or within RNA splicing and mRNA processing. Predicted to be located in nucleus. Predicted to be part of U2-type catalytic step 2 spliceosome. Predicted to colocalize with chromatin. Is expressed in genitourinary system. Orthologous to human BUD31 (BUD31 homolog). [provided by Alliance of Genome Resources, Apr 2022]
