Prp3b is part of the U2 small nuclear ribonucleoproteins complex (U2 snRNP) Prp8 functions as a scaffold which mediates the ordered assembly of spliceosomal proteins and snRNAs. For details see Prp8 Prp18 and Bud31 are essential for the catalytic step in pre-mRNA splicing process. snRNA-associated-splicing factor 24 binds preferentially to the U4/U6 hybrid snRNAs. For details see Prp24 For Prp19 see Prp19 For Prp20 see Srp20-Human Alternative Splicing Factor Prp31 functions in forming the U4/U5-U6 tri-snRNP. For Prp40 see Prp40. Prpcwc2 is a yeast splicing factor which plays a role in the generation of a functional splicing center Prp RBM22 is the human homolog of Prpcwc2. Prpcwc26 or Bud13 belongs to the pre-mRNA retention and splicing complex RES. Disease Mutations in Prp8 and Prp31 cause retinitis pigmentosa. Structural highlights Prp8 is a multi-domain protein containing an RNA-binding domain and a Jab1/MPN domain.
