. N-terminal mutants of herpes simplex virus type 2 gH are transported without gL but require gL for function. J Virol. 2007;81:5102-11 pubmed
..Additional mutagenesis identified L66 and L72 as important for function. Together, our results highlight several key gH residues: R39, Y41, W42, and D44 for gH transport and L66 and L72 for gH/gL structure and function...

..These data were interpreted to suggest, first, that HSV-2 US4 represents an ancient gene of alpha herpesviruses, and, more tentatively, that the evolution of the genes for gG and gD may have proceeded through a duplication event. ..

..The results show that the UL41 genes of strains G and 17 are 86% homologous and that the lack of shutoff by HG52 is likely to be explained by a frameshift mutation within its UL41 coding sequence...

..Several recognize important functional domains of gH2, gL2, or the complex. We suggest a common grouping scheme for all of the known MAbs against gH/gL of both HSV-1 and HSV-2...

. Regulation of herpes simplex virus gB-induced cell-cell fusion by mutant forms of gH/gL in the absence of gD and cellular receptors. MBio. 2013;4: pubmed publisher
..Here, we show that a mutant form of gH/gL, gH?48/gL, can induce fusion of gB-expressing cells in the absence of gD and a gD receptor. Our study supports the concept that gB is the HSV fusogen and its activity is regulated by gH/gL. ..

..Therefore, we consider that this ORF represents an additional HSV gene (UL49A) with counterparts in all sequenced alpha-, beta- and gammaherpesviruses...
