1.G.17 The Bovine Leukemia Virus Envelope Glycoprotein (BLV-Env) Family

This family includes envelop glycoproteins of variable sizes due to proteolytiprocessing.  The actual fusion peptide is 24 aas long (Apellániz et al. 2014).  It derives from gPr72 of 341 aas which is an Env protein fragment that is further degraded to the envelope glycoprotein, Env-GP of 127 aas (acc# L0R354) and then to the fusion peptide.
