We downloaded the proteins associated with "Erythrocyte membrane protein" from the UniProt database. We then used the MEME local version tool to compare them one by one to the viral proteins to identify conserved domains. We combined the motifs by protein and domain. As shown in Table , the E, ORF3a, ORF7a, ORF7b, and ORF8 proteins all contain the Band_3_cyto domain (IPR013769). Band_3_cyto is the cytoplasmic domain of the Band 3 anion exchange protein, which is responsible for the exchange of Cl-/HCO3-ions. Band 3's cytoplasmic domain serves primarily as a docking site for other membrane-associated proteins. Ankyrin, protein 4.2, protein 4.1, and hemoglobin are all protein ligands for cdb3. E has a shorter Band_3_cyto domain that serves as the heme-binding domain. Band_3_cyto domains are absent from the S and M proteins. ORF7a and ORF7b have Band_3_cyto domains that overlap with their 4.1m domains, respectively. ORF3a have Band_3_cyto domains that are in or near the transmembrane region. The search results for "Erythrocyte membrane protein"-related proteins also indicates that the M protein contains a FERM domain (residues 20-130, 178-216). F is an abbreviation for 4.1 protein. .1 proteins are associated with spectrin.
