ubiquitin-like (Ubl) domain found in ubiquitin carboxyl-terminal hydrolase 24 (UBP24) and similar proteins
UBP24 (EC 3.4.19.12), also termed deubiquitinating enzyme 24, or ubiquitin thioesterase 24, or ubiquitin-specific-processing protease 24 (USP24), is a deubiquitinating protein that interacts with damage-specific DNA-binding protein 2 (DDB2) and regulates DDB2 stability. It may also play a role in the pathogenesis of Parkinson's disease (PD). UBP24 proteins contain an N-terminal ubiquitin-associated (UBA) domain, a ubiquitin-like (Ubl) domain, and a C-terminal peptidase C19 domain.
Feature 1: key conserved lysine K27, 1 residue position
Conserved feature residue pattern:[KR]
Evidence:
Comment:K27/R (Ub numbering) is a lysine conserved in the Ubl_ubiquitin_like family; it is one of 7 lysines involved in chain linkage in ubiquitin (K6, K11, K27, K29, K33, K48, or K63, Ub numbering); may have other functions, for example for NEDD8 it is involved in the mechanism of protein neddylation
