Retinitis pigmentosa 9 (autosomal dominant), also known as RP9 or PAP-1, is a protein which in humans is encoded by the RP9 gene.[5]

Function

The removal of introns from nuclear pre-mRNAs occurs on a complex called a spliceosome, which is made up of 4 small nuclear ribonucleoprotein (snRNP) particles and an undefined number of transiently associated splicing factors. The exact role of PAP-1 in splicing is not fully understood, but it is thought that PAP-1 localizes in nuclear speckles containing the splicing factor SC35 and interacts directly with another splicing factor, U2AF35.[6]

Clinical significance

Mutations in PAP1 underlie autosomal dominant retinitis pigmentosa mapped to the RP9 gene locus.[7]

Interactions

RP9 has been shown to interact with U2 small nuclear RNA auxiliary factor 1.[6]
