| Popis: | Rat FAD-dependent sulfhydryl oxidase was purified; partial sequencing indicated that it was homologous to human quiescin Q6. A cDNA (GenBank accession no. AF285078) was cloned from rat seminal vesicles, and active recombinant sulfhydryl oxidase was expressed in Chinese hamster ovary epithelial cells. This 2472-nucleotide cDNA has an open reading frame of 1710 base pairs, encoding a protein of 570 amino acids including a 32-amino acid leader sequence and two potential sites for N-glycosylation. One of them is used and the 64,000 M(r) purified protein was transformed to 61,000 by the action of endoglycosidase F. Northern blotting and reverse transcription-polymerase chain reaction analyses showed that there were small amounts of sulfhydryl oxidase in the rat testis, prostate, lung, heart, kidney, spleen, and liver, and that the gene was highly expressed in seminal vesicles and epididymis. Rat sulfhydryl oxidase cDNA corresponds to the human cell growth inhibiting factor cDNA, which could be a differently spliced form of quiescin Q6. Comparing sulfhydryl oxidase sequences with those of human quiescin Q6 and mammalian and Caenorhabditis elegans quiescin Q6-related genes established the existence of a new family of FAD-dependent sulfhydryl oxidase/quiescin Q6-related genes containing protein-disulfide isomerase-type thioredoxin and yeast ERV1 domains. |
