Genetic mapping of a mouse chromosomal locus required for mink cell focus-forming virus replication

Mouse-hamster somatic cell hybrids were used to show that the recombinant mink cell focus-forming murine leukemia viruses and their ecotropic virus progenitors require different mouse chromosomes for replication. Mouse chromosome 1 was shown to carry the genetic information necessary for the replication of six different mink cell focus-forming isolates, and this gene, designated Rmc-1, was tentatively positioned at the distal end of the chromosome.
