Fig. 8. Envelope transmembrane (TM) protein sequences alignment for syncytin-A, syncytin-B, and representatives of endogenous and exogenous retroviruses. Sequences were aligned by using the clustalw program. GenBank accession nos. are: Murine GLN sequences (XM_109749); Mus musculus endogenous retrovirus (MmERV, AL844168); murine MuRRS sequences (XM_137084); murine MuRVY sequences (X87639); endogenous murine mammary tumor virus (endoMMTV, Mtv1, AF228550); endogenous murine leukemia virus (endoMLV, Emv-2, AC122266); murine intracisternal A-particle-related elements with an envelope gene (IAPE, M73818); and human sequences HERV-F (HERVFH19 RepBase consensus), HERV- 9 (HERV9 RepBase consensus), HERV-H (AJ289709), HERV-FRD (AL136139), HERV-W (AC000064), HERV-Fc (AL354685), HERV-R (AC073210), HERV-Rb (AC093488), HERV-K (HML2, AC072054), HERV-T (AC078899), and human immunodeficiency virus (HIV-1, HIVBRUCG).
