Protein function

Participates in pre-mRNA splicing. Part of the U4/U5/U6 tri-snRNP complex, one of the building blocks of the spliceosome.

Protein tissue specificity

Highly expressed in retina, liver, kidney and blood. Detected at lower levels in heart and brain.

Protein sequence and domain

Contains 1 PWI domain.

Protein post-translational modifications

Ubiquitinated. Undergoes ‘Lys-63’-linked polyubiquitination by PRPF19 and deubiquitination by USP4. ‘Lys-63’-linked ubiquitination increases the affinity for PRPF8 and may regulate the assembly of the U4/U6-U5 tri-snRNP complex.

Protein cellular localization

Nucleus speckle. Note: Colocalizes with spliceosomal snRNPs.


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. This gene product is one of several proteins that associate with U4 and U6 snRNPs. Mutations in this gene are associated with retinitis pigmentosa-18.
