翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク USP9Y ： ウィキペディア英語版 USP9Y Ubiquitin specific peptidase 9, Y-linked (fat facets-like, Drosophila), also known as USP9Y, is an enzyme which in humans is encoded by the ''USP9Y'' gene.〔 It is required for sperm production. This enzyme is a member of the peptidase C19 family and is similar to ubiquitin-specific proteases, which cleave the ubiquitin moiety from ubiquitin-fused precursors and ubiquitinylated proteins. == Clinical significance == Mutations in this gene have been associated with Sertoli cell-only syndrome (SCO) and male infertility.〔(【引用サイトリンク】 url = http://www.ncbi.nlm.nih.gov/sites/entrez?Db=gene&Cmd=ShowDetailView&TermToSearch=8287 )〕 The USP9Y gene is found on the azoospermia factor (AZF) region on the Y chromosome. Men who have impaired or no sperm production often have a deletion in the AZF region, especially in the USP9Y gene, and it was thought that USP9Y was necessary for sperm production. However, a man and his father with a USP9Y deletion who could produce sperm were recently reported. The corresponding gene is present but inactive in chimpanzees and bonobos. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「USP9Y」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
