  • Function

    Transcriptional coactivator for steroid nuclear receptors ESR1/ER-alpha and ESR2/ER-beta, and JUN/AP-1 (By similarity). May be involved in pre-mRNA splicing process.
  • Tissue specificity

    Widely expressed. Highly expressed in pancreas, skeletal muscle, lung and brain. Expressed at intermediate level in kidney, liver and heart.
  • Sequence similarities

    Belongs to the splicing factor SR family.
    Contains 3 RRM (RNA recognition motif) domains.
  • Cellular localization

    Nucleus speckle. Concentrated in nuclear speckles. Colocalizes with the core spliceosomal snRNP proteins.
