USP9Y
Ubikvitin-specifična Y-vezana peptidaza 9 (masnofacetna drozofilska), znana i kao USP9Y, je enzim koji je kod ljudi kodiran genom USP9Y.[5] Potreban je za proizvodnju sperme. Ovaj enzim je član porodice peptidaza C19 i sličan je ubikvitinspecifičnim proteazama, koje cijepaju ostatak ubikvitina od prekursora koji su spojeni s ubikvitinom i ubikvitiniliranih proteina.
Klinički značaj
urediMutacije u ovom genu povezane su sa sindromom sindromom sa samo Sertolijevim ćelijama (SCO) i muškom neplodnošću.[5]
Gen USP9Y nalazi se na području faktora azospermije (AZF) na hromosomu Y. Muškarci koji imaju oštećenu ili nemaju proizvodnju sperme često imaju |deleciju u AZF regiji, posebno u genu USP9Y, a smatralo se da je USP9Y neophodan za proizvodnju sperme. Međutim, nedavno su prijavljen muškarac i njegov otac koji su imali deletirani USP9Y koji bi mogli proizvesti spermu. Odgovarajući gen prisutan je, ali neaktivan kod običnih čimpanzi i bonoboa.[6][7]
