abstractText | Full text of MNL contribution: Biochemical variants: a) Hexokinase. A genetically determined electrophoretic variant of hexokinase-1 has been found in some mice of the Peru/Coppock stock. This variant has less anodal electrophoretic mobility than hexokinase-1 from all other inbred strains and stocks tested. Genetic analyses indicate that the variant is determined by an autosomal codominant gene. We propose that the common allele is designated Hk-la and the variant allele found in Peru/Coppock mice Hk-1b. The electrophoretic mobility of hexokinase-1 appears to be modified in testis where it has a faster anodal mobility than in kidney extracts. In addition a sperm specific hexokinase is also found. These effects are only found in testes where spermatogenesis is unimpaired since in males heterozygous for T(1;7)40H and T(11;19)42H which do not form spermatoza (Searle, A.G. et al., 1978. Ann. Biol. Anim. Bioch. Biophys. 18: 391) and in males under six weeks of age the electrophoretic mobility of hexokinase-1 is unmodified in testis and sperm specific hexokinase is not found. In heterozygotes for T(5;12)31H where reduced numbers of spermatozoa are found there is reduced activity of sperm specific hexokinase and both the modified and unmodified forms of hexokinase-1 occur in testis.
