U4/U6 small nuclear ribonucleoprotein Prp3 (IPR027104)

Short name: Prp3

Overlapping homologous superfamilies


Family relationships



Prp3 (also known as PRP3) participates in pre-mRNA splicing [PMID: 9328476]. It may play a role in the assembly of the U4/U5/U6 tri-snRNP complex [PMID: 9326489]. Defects in PRPF3 are the cause of retinitis pigmentosa type 18 (RP18). RP leads to degeneration of retinal photoreceptor cells [PMID: 11773002, PMID: 12714658, PMID: 17932117]. In Arabidposis thaliana, protein RDM16 acts as a pre-mRNA splicing factor and functions in RNA-directed DNA methylation by influencing Pol V transcript levels [PMID: 24068953].
