CYLD lysine 63 deubiquitinase, also known as CYLD, is a human gene.This gene 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. [Source: Wikipedia
