Protein
Pre-mRNA-splicing factor 38
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Function
Required for pre-mRNA splicing and maintenance of stable U6 small nuclear RNA levels. Implicated in the formation of stable and biologically active snRNP structures. As part of the U4/U6.U5 tri-snRNP particle, dispensible for spliceosome assembly, but required for conformational changes, which result in U4 snRNA release and the subsequent catalytic activation of the spliceosome.
Similarity
Belongs to the PRP38 family.
