Area: Virology Recent study addresses the interaction of glycoproteins in the replication of HSV In the replication of Herpes Simplex Virus (HSV)-1 glycoprotein K (gK) and the UL20 protein (UL20p) are required. A recent study in the Journal of Virology investigated the interaction of the N-terminal amino acids of gKa together with the extracellular portions of the proteins gB, gD, or gH, respectively. The study implies that the gK/UL20p protein complex directly interacts with gB and gH. The HSV gD Envelope Protein antibody that has been utilized in this study is from Firma Virusys and available at antibodies-online. Additional antibodies against HSV gD are available here: HSV gD antibodies. The publication can be found below: Source: J Virol. 2010 Jun 23.
