== Publication Abstract from PubMed == | |||
ERp44 mediates thiol-dependent retention in the early secretory pathway, forming mixed disulphides with substrate proteins through its conserved CRFS motif. Here, we present its crystal structure at a resolution of 2.6 A. Three thioredoxin domains-a, b and b'-are arranged in a clover-like structure. A flexible carboxy-terminal tail turns back to the b' and a domains, shielding a hydrophobic pocket in domain b' and a hydrophobic patch around the CRFS motif in domain a. Mutational and functional studies indicate that the C-terminal tail gates the CRFS area and the adjacent hydrophobic pocket, dynamically regulating protein quality control. | |||
Crystal structure of human ERp44 shows a dynamic functional modulation by its carboxy-terminal tail.,Wang L, Wang L, Vavassori S, Li S, Ke H, Anelli T, Degano M, Ronzoni R, Sitia R, Sun F, Wang CC EMBO Rep. 2008 Jul;9(7):642-7. Epub 2008 Jun 13. PMID:18552768<ref>PMID:18552768</ref> | |||
