Jun 01, 2020 · This observation led to the test for cell–cell fusion without the viral background using transfected fibroblasts and therefore defined the minimal set of HSV-1 proteins involved in membrane fusion as gD, gB and gH/L being both necessary and sufficient to mediate plasma membrane fusion . As those proteins do not share any structural similarity, the theory is that during fusion, each protein is …

Apr 16, 2012 · ER–ER fusion is delayed in cells missing Sey1p. (a) Wild-type cells of opposite mating types expressing either ss-RFP-HDEL or cytosolic GFP were mixed, placed on an agarose pad, and imaged at 1-min intervals. Selected images from the time-lapse video are shown. Time 0 is the first image taken after cell fusion, as indicated by GFP in both cells

The pre-fusion conformation of HAP2 remains unknown, however, and it is possible that the non-polar residues of the two fusion loops are maintained unexposed until the time of fusion. The conserved interaction of the R 185 side chain with that of the E 126 residue in the tip domain may allow exposure of the two fusion loops only after a

the membrane-proximal region (mpr) ofherpes simplex virus

Glycoprotein B (gB), gD, and gH/gL constitute the fusion machinery of herpes simplex virus (HSV). Prior studies indicated that fusion occurs in a stepwise fashion whereby the gD/receptor complex activates the entire process, while gH/gL regulates the fusion reaction carried out by gB. Trimeric gB is a class III fusion protein. Its ectodomain of 773 amino acids contains a membrane-proximal
