HGNC name PRP40 pre-mRNA processing factor 40 homolog A (S. cerevisiae)
HGNC id 16463
PROTEIN
PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • a N terminal PGM (proline, glycine, methionine) rich region
  • tandem WW motifs
  • three FF domains (a 60 amino acid residue phosphopeptide-binding module), composed of three alpha helices arranged in an orthogonal bundle with a 3(10) helix in the loop between the second and third alpha helices
  • two bipartite nuclear localization signals, FB3HM and FB3HC domains
    • conjugated PhosphoP
    HOMOLOGY
    interspecies homolog to murine Prpf40a (96.7pc)
    homolog to rattus Prpf40a (96.9pc)

    FAMILY
  • PRPF40 family
    • CATEGORY RNA associated
    SUBCELLULAR LOCALIZATION     intracellular
    intracellular,nucleus,nucleoplasm,nuclear bodies,nuclear speckles
    basic FUNCTION
  • involved in spliceosome function
  • pre-mRNA splicing protein
  • regulating localization of WASL, thus negatively regulating the function of WASL in the cytoplasm
    • CELLULAR PROCESS nucleotide, RNA splicing
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
    a component the first WW domain of FBP11/HYPA (FBP11 WW1) is essential for preventing severe neurological diseases such as Huntington disease and Rett syndrome (Kato 2006)
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • huntingtin, N terminal proline rich segment, enhanced by lengthening the adjacent glutamine tract
  • WASL(colocalization with WASL)
  • interacting with the phosphorylated carboxyterminal domain of POLR2A
  • interacting with SF1, SRPK1 CARD8, ATBF1 and MECP2
  • associating with AKAP8L in brain (Sayer 2005)
  • interacting with AKAP8L (AKAP8L/PRPF40A scaffold is a potential nuclear docking site for huntingtin protein and may contribute to the nuclear accumulation of huntingtin observed in Huntington disease)
    • cell & other
