Syntheny and localization of the following genes in common shrew Sorex araneus were determined: isocitrate dehydrogenase 2 (IDH2), acid phosphatase 2 (ACP2), glutamine--pyruvate--oxo-acid transaminase (GPT), and inorganic pyrophosphatase (PP) on chromosome ik; adenylate kinases 1 and 3 (AK1 and AK3) on chromosome af; and enolase 1 (ENO1) on chromosome jl. Two genes were assigned to definite arms: aminoacylase 1 (ACY1) to arm p of chromosome mp and glutamic-oxaloacetic transaminase 1 (GOT1) to arm q of chromosome qr. Thus, 26 genes marking eight out of ten chromosomes are present now on the cytogenetic map of common shrew. These include previously described localizations. Show less

This report extends the genetic map of the common shrew (Sorex araneus) by use of a clone panel of shrew-Chinese hamster and shrew-mouse hybrid cells (Pack et al., 1995; Matyakhina et al., 1996). This set of hybrid clones made it possible to assign the shrew genes for isocitrate dehydrogenase 2 (IDH2), inorganic pyrophosphatase (PP), glutamicpyruvate transaminase (GPT), adenosine kinase (ADK), glucuronidase 2 (GUSB) and acid phosphatase 2 (ACP2) to chromosome ik; the genes for adenylate kinases 1 and 3 (AK1 and AK3) to chromosome af; the genes for glutamate-oxaloacetate transaminase 2 (GOT2), peptidase D (PEPD) and growth hormone (GH) to chromosome hn; the gene for phosphoglucomutase 2 (PGM2) to chromosome go, the gene for enolase 1 (ENO1) to chromosome ji, the gene for ornithine carbamoyl-transferase (OTC) to chromosome de, the gene for aminoacylase 1 (ACY1) to arm m (chromosome mp), the gene for glutamate-oxaloacetate transaminase 1 (GOT1) to arm q (chromosome qr). Thus, the genetic map of the common shrew now contains 33 genes and it is possible to compare the syntenic associations with other species. Show less
