Serine/Arginine Rich Splicing Factor 17A (SRSF17A)

In the 2.6-megabase segment of the distal short arms of the X and Y chromosomes, called the pseudoautosomal region, Ellison et al. (1992) identified an expressed gene designated XE7.  Ellison et al. (1992) reported the structure of the XE7 gene and its expression in various human tissues. The analysis of genomic and cDNA clones showed that alternative RNA splicing results in the production of 2 protein isoforms, one containing 385 amino acids and the other containing 695 residues. The smaller polypeptide is a truncated version of the larger and results from the inclusion of a cassette exon that has an in-frame stop codon. The XE7 gene appears to be ubiquitously expressed, and the production of both protein isoforms was predicted in each of the several tissues examined.
