SRFBP1 contains 7 WD repeats and belongs to the WD repeat STRAP family. SRFBP1 may play a role in the cellular distribution of the SMN complex. The SMN complex plays an essential role in spliceosomal snRNP assembly in the cytoplasm and is required for pre-mRNA splicing in the nucleus. SRFBP1 negatively regulates TGF-beta signaling but positively regulates the PDPK1 kinase activity by enhancing its autophosphorylation and by significantly reducing the association of PDPK1 with 14-3-3 protein. SRFBP1 may be involved in regulating transcriptional activation of cardiac genes during the aging process. It also may play a role in biosynthesis and/or processing of SLC2A4 in adipose cells.
