MGI Phenotype FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes an RNA polymerase II-associated protein. The encoded protein may function in transcriptional regulation and may also regulate apoptosis. Alternatively spliced transcript variants have been described. [provided by RefSeq, Mar 2009]

Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to T transversion at position 810 of the Rpap3 transcript in exon 7 of 17 total exons.  The mutated nucleotide causes a glutamic acid to valine substitution at amino acid 241 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction
The Rpap3 gene encodes a 660 amino acid protein that belongs to the RPAP3 (RNA polymerase II-associated protein) family. RPAP3 forms an interface between the RNA polymerase II enzyme and chaperone/scaffolding protein, suggesting that it is required to connect RNA polymerase II to regulators of protein complex formation. The protein contains seven TPRs (tetratrico peptide repeats) at amino acids 8-41, 134-167, 169-201, 202, 235, 284-317, 319-351, and 352-385. These repeats mediate protein-protein interactions and the assembly of multiprotein complexes (Uniprot Q9D706). 
The E241V change is predicted to be probably damaging by the PolyPhen program.
