Protein detail:


Protein name ORF7a protein
Uniprot protein ID P0DTC7
Protein length 121 amino acids
Protein description The orf 7a of SARS-CoV-2 is a transmembrane protein with four regions from the N-terminal: 1) the first 15 amino acids form a signal peptide which is hydrolyzed by the infected host cells; 2) the amino acids from 16 to 96 constitute the intracellular domain; 3) the 97- 117 amino acids are hydrophobic amino acids constituting a transmembrane domain; and 4) the last five amino acids constitute the C- terminal of the orf7a. The orf7a interacts with the S, M, E, and the orf3a proteins, which suggest a role of the protein in the assembling of the virus and in the binding and invasion of the virus to the host cells.

Evidence The mutational probabilities of these 118 sites across all time points (month-wise) were visualized using a clustered heatmap where six clusters were obtained with 4, 3, 2, 5, 5, and 99 sites per cluster (Figure 1A,B and Table S2).
