It is essential for the formation of the spliceosome hPRP31 is associated with the U4\/U6 di-snRNP and interacts with another splicing factor, hPRP6, to form the U4\/U6-U5 tri-snRNP. It has been shown that when hPRP31 is knocked down by RNAi, U4\/U6 di-snRNPs accumulate in the Cajal bodies and the U4\/U6-U5 tri-snRNP cannot form.[6]PRPF31 is recruited to introns following the attachment of U4 and U6 RNAs and the 15.5K protein NHP2L1. The addition of PRPF31 is crucial for the transition of the spliceosomal complex to the activated state.[7]       (adsbygoogle = window.adsbygoogle || []).push({});after-content-x4Clinical significance[edit]A mutation in PRPF31 is one of 4 known mutations in splicing factors which are known to cause retinitis pigmentosa. The first mutation in PRPF31 was discovered by Vithana et al. in 2001.[5] Retinitis pigmentosa (RP) is a clinically and genetically heterogeneous group of retinal dystrophies characterized by a progressive degeneration of photoreceptors, eventually resulting in severe visual impairment.[8]Inheritance[edit]Mutations in PRPF31 are inherited in an autosomal dominant manner, accounting for 2.5% of cases of autosomal dominant retinitis pigmentosa (adRP) in a mixed UK population.[9] However, the inheritance pattern of PRPF31 mutations is atypical of dominant inheritance, showing the phenomenon of partial penetrance, whereby a dominant mutations appear to “skip” generations. This is thought to be due to the presence of two wild type alleles, a high-expressivity allele and a low-expressivity allele. If a patient has a mutant allele and a high-expressivity allele, they do not show disease phenotype. If a patient has a mutant allele and a low-expressivity allele, the residual level of protein falls beneath the threshold for normal function, and so they do show disease phenotype. The inheritance pattern of PRPF31 can therefore be thought of as a variation of haploinsufficiency. This variant of haploinsufficiency is only seen in two other human diseases: Erythropoietic protoporphyria, caused by mutations in the FECH gene; and hereditary elliptocytosis, caused by mutations in the spectrin gene.[10][11]References[edit]^ a b c ENSG00000105618 GRCh38: Ensembl release 89: ENSG00000275885, ENSG00000105618 – Ensembl, May 2017^ a b c GRCm38: Ensembl release 89: ENSMUSG00000008373 – Ensembl, May 2017^ “Human PubMed Reference:”.
