The quantitative differences between the activity of the 3 common phenotypes of human red cell GPT has been confirmed. In addition, the activity of red cell GPT 1 was found to be greater in young children than in adults. No such difference was found for the GPT 2 phenotype. The activity of the red c

β¦ Synopsis
Three alleles at the Gpt-1 (glutamic-pyruvic transaminase-1) locus in the mouse, as identified by electrophoresis on cellulose acetate, and their distribution among inbred mouse strains and wild stocks are described. The Gpt-1 locus was shown to control the soluble form of the enzyme. Three-point linkage analysis established the location of Gpt-1 on chromosome 15 between uw and bt. In addition, a new staining procedure is described that allows the visualization of GPT activity on gels by the deposition of formazan. This is an improvement over previous methods that produced bands of nonfluorescenee against a fuorescent background.

The human RAPIA gene encodes a protein that apparently can antagonize the function of oncogenic ras genes in gene transfer experiments, but its normal function is unknown. To understand the function of this gene, we have undertaken a study of the mouse homolog, Rapla. The complete coding sequence of
