ubiquitin-like (Ubl) domain found in AN1-type zinc finger protein 4 (ZFAND4) and similar proteins
ZFAND4, also termed AN1-type zinc finger and ubiquitin domain-containing protein-like 1 (ANUBL1), may function as an oncogene that promotes proliferation and regulates relevant tumor suppressor genes in gastric cancer, suggesting a role in gastric cancer initiation and progression. ZFAND4contains an N-terminal ubiquitin-like (Ubl) domain with a beta-grasp Ubl fold, a common structure involved in protein-protein interactions, as well as a C-terminal AN1-type zinc finger. Unlike ubiquitin polyproteins and most ubiquitin fusion proteins, the N-terminal Ubl domain of ZFAND4 does not undergo proteolytic processing.
Feature 1: key conserved lysine K27, 1 residue position
Conserved feature residue pattern:[KR]
Evidence:
Comment:K27 (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
