This entry includes Pre-mRNA-splicing factor BUD31, also known as G10 protein, and its homologues. BUD31 is involved in the pre-mRNA splicing process [1-3] and it is highly conserved in a wide range of eukaryotic species. Human BUD31 may play a role as a regulator of androgen receptor (AR) transcriptional activity, probably increasing the AR transcriptional activity [4].
