Though the inbred DDD mouse strain is essentially of the N type, the primary culture of this strain was about 100-fold more sensitive to B-tropic WN1802B virus than were the typical N-type strains (C3H/He, C57L, etc.). After cloning, DDD mouse cells segregated two types of cells, typical N-type cells and cells lacking in Fv-1 restriction. As both types of cells so far tested retained glucose-6-phosphatase-1 coded by a locus closely linked to Fv-1 and genetic cross experiments indicated the presence of a gene(s) modifying the Fv-1 phenotype, variation in Fv-1 restriction could presumably be brought about by genetic changes in a gene(s) other than Fv-1 itself. N-type and dually permissive cell clones were similarly established from the inbred G mouse. Compositions of polypeptides labeled with [35S]methionine in the N-type and dually permissive cells of DDD and G mouse origins were compared by two-dimensional gel electrophoresis. The polypeptide maps of these cells were similar except for a few spots. Among these dissimilar spots, a spot of about 20,000 daltons with a pI of about 5.5 was always present in N-type cells, whereas it was absent in dually permissive cells. In DDD mouse-derived clones, a proportional relation was observed between the intensity of the spot and the restriction to the B-tropic virus.
