  • Function

    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. Binds to poly(A) RNA.
  • Tissue specificity

    Ubiquitously expressed, at various levels depending on the isoform and the tissue.
  • Sequence similarities

    Contains 1 RRM (RNA recognition motif) domain.
  • Domain

    The RRM domain is necessary for interaction with SMAD4. Both the RRM domain and the C-terminus are required for TGFB1/Smad-mediated transactivation activity.
  • Cellular localization

    Nucleus. Cytoplasm.
