Nature of Mutation

DNA sequencing using the SOLiD technique identified an A to G transition at position 4572 of the Psme4transcript in exon 38 of 47 total exons. Multiple transcripts of the Psme4gene are displayed on Ensembl and Vega. The mutated nucleotide causes a glutamic acid to glycine substitution at amino acid 1455 of the encoded protein. The mutation has been confirmed by DNA sequencing using the Sanger method (Figure 1).

Protein Function and Prediction

The Psme4 gene encodes two isoforms of a protein that activates proteasomal cleavage of peptides in an energy-independent manner. Isoform 1 contains 1843 amino acids. The protein is involved in spermatogenesis and may be involved in DNA repair. PSME4 contains six HEAT repeats and a bipartite nuclear targeting sequence (Uniprot Q5SSW2). Knockout mice are viable and show no obvious developmental abnormalities. They have reduced male fertility due to defects in spermatogenesis in meiotic spermatocytes and during the maturation of postmeiotic haploid spermatids.

The E1455G change is located between the fourth and fifth HEAT domains, and is predicted to be probably damaging by the PolyPhen program.
