Xylosyl transferase 2 는 인간에서 XYLT2 유전자 에 의해 인코딩되는 효소 다.[5] [6]
함수 이 유전자가 인코딩한 단백질은 자일로실전달효소의 이소형태로 글리코실전달효소 계열에 속한다. 이 효소는 실로이스를 UDP-xylose 에서 코어 단백질의 특정 세린 잔류물로 전달하고 콘드로이틴 황산염 , 헤파란 황산염 , 헤파린, 피부염 황산염 을 포함한 프로테오글리칸 의 글리코사미노글리칸 체인의 생합성을 개시한다.[6]
임상적 유의성 경화증 환자에게서 증가되는 효소 활성은 전신 경화증에서 경화증 활성을 판별하는 진단 표식이다.[6]
이 유전자의 돌연변이가 스폰디로-구체 증후군 의 원인인 것으로 밝혀졌다.[7] 그것은 또한 가독산토마 탄성체 의 공작용제로 연루되었다.
