Protein detail:


Protein name Membrane Glycoprotein
Uniprot protein ID P0DTC5
Protein length 222 amino acids
Protein description The membrane protein is present in high amounts out of all proteins in coronaviruses . Its length spans to about 220-260 amino acids with a short length N terminal domain, attached to triple transmembrane domains that are further connected to a carboxyl-terminal domain and belong to the N-linked glycosylated proteins with a conserved domain of 12 amino acids. Out of the three TDM, the first one is capable enough to encourage self-association of M proteins, improved membrane affinity, and retention in Golgi. The membrane protein is a transmembrane glycoprotein, is the most abundant structural protein in the virus particle and has been suggested as an antiviral drug target.

Evidence We further analyzed the sequence data for the presence of iSNVs in the three samples. We detected four iSNVs (C8481T, C22000A, T26975G and G28812T - Figure 1B) in the pharyngeal swab and sputum samples, three (C8481T, C22000A, and G28812T) of which have been identified as SNP sites previously. [7] These four iSNVs were located in the ORF1a, S, M and N genes, respectively, and led to nonsynonymous mutations (Figure 1B)
