摘要
Four human RAS-like cDNAs and a mouse genomic DNA fragment were used to define novel mouse Ras-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 of Ras-like and/or G protein genes were identified, on Chrs 9 and 17. © 1991 Springer-Verlag New York Inc.
