Structural highlights
Function
[VEMP_CVHSA] Component of the viral envelope that plays a central role in virus morphogenesis and assembly. It is sufficient to form virus-like particles. Seems to be important for creating the membrane curvature needed to acquire the rounded, stable and infectious particle phenotype. Acts as a viroporin, inducing the formation of hydrophilic pores in cellular membranes. Also induces apoptosis (By similarity).
Publication Abstract from PubMed
Coronaviruses (CoV) cause common colds in humans, but are also responsible for the recent Severe Acute, and Middle East, respiratory syndromes (SARS and MERS, respectively). A promising approach for prevention are live attenuated vaccines (LAVs), some of which target the envelope (E) protein, which is a small membrane protein that forms ion channels. Unfortunately, detailed structural information is still limited for SARS-CoV E, and non-existent for other CoV E proteins. Herein, we report a structural model of a SARS-CoV E construct in LMPG micelles with, for the first time, unequivocal intermolecular NOEs. The model corresponding to the detergent-embedded region is consistent with previously obtained orientational restraints obtained in lipid bilayers and in vivo escape mutants. The C-terminal domain is mostly alpha-helical, and extramembrane intermolecular NOEs suggest interactions that may affect the TM channel conformation.
