Ras-like genes and gene families in the mouse

Abstract
Four humanRAS-like cDNAs and a mouse genomic DNA fragment were used to define novel mouseRas-like genes and gene families. Inheritance of DNA restriction fragment length variants associated with these genes in recombinant inbred and backcross mice allowed definition of 12 genetic loci, nine of which were mapped, to chromosomes (Chr) 2, 4, 7, 8, 9, and 17. Two possible clusters ofRas-like and/or G protein genes were identified, on Chrs 9 and 17.
