DESCRIPTION

Also known as RBPMS_HUMAN, RBPMS, HERMES. Acts as a coactivator of transcriptional activity. Required to increase TGFB1/Smad-mediated transactivation. Acts through SMAD2, SMAD3 and SMAD4 to increase transcriptional activity. Increases phosphorylation of SMAD2 and SMAD3 on their C-terminal SSXS motif, possibly through recruitment of TGFBR1. Promotes the nuclear accumulation of SMAD2, SMAD3 and SMAD4 proteins (PubMed:26347403). Binds to poly(A) RNA (PubMed:17099224, PubMed:26347403). Homodimer; each protein chain binds one RNA molecule via the external surface of the homodimer (PubMed:26347403). Interacts with SMAD2, SMAD3 and SMAD4; the interactions are direct (PubMed:17099224).
