Function

See also: U4 spliceosomal RNA and U6 spliceosomal RNA

The removal of introns from nuclear pre-mRNAs occurs on complexes called spliceosomes, which are made up of 4 small nuclear ribonucleoprotein (snRNP) particles and an undefined number of transiently associated splicing factors. PRPF3 is one of several proteins that associate with U4 and U6 snRNPs.[supplied by OMIM]^[5]

Interactions

PRPF3 has been shown to interact with DVL3.^[6]
