該基因編碼一種細胞質蛋白，具有三個細胞骨架相關蛋白-甘氨酸保守（cap-gly）結構域，作為一種去氫酶。該基因突變與圓筒狀瘤、多發性家族性毛發上皮瘤和brooke-spiegler綜合征有關。交替轉錄剪接變體，編碼不同的亞型，已經被描述出來。[由RefSeq提供，2008年7月]
This gene is encodes a cytoplasmic protein with three cytoskeletal-associated protein-glycine-conserved (CAP-GLY) domains that functions as a deubiquitinating enzyme. Mutations in this gene have been associated with cylindromatosis, multiple familial trichoepithelioma, and Brooke-Spiegler syndrome. Alternate transcriptional splice variants, encoding different isoforms, have been characterized. [provided by RefSeq, Jul 2008]
