CHROMOSOME LOCATION OF 16 GENES IN THE COMMON SHREW, SOREX-ARANEUS L (MAMMALIA, INSECTIVORA)

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 hyb rid cells (Pack et al., 1995; Matyakhina et al., 1996). This set of hy brid clones made it possible to assign the shrew genes for isocitrate dehydrogenase 2 (IDH2), inorganic pyrophosphatase (PP), glutamic pyruv ate transaminase (GPT), adenosine kinase (ADK), glucuronidase 2 (GUSB) and acid phosphatase 2 (ACP2) to chromosome ik; the genes for adenyla te kinases 1 and 3 (AK1 and AK3) to chromosome af; the genes for gluta mate-oxaloacetate transaminase 2 (GOT2), peptidase D (PEPD) and growth hormone (GH) to chromosome hn; the gene for phosphoglucomutase 2 (PGM 2) to chromosome go, the gene for enolase 1 (ENO1) to chromosome jl, t he gene for ornithine carbamoyl-transferase (OTC) to chromosome de, th e gene for aminoacylase 1 (ACY1) to arm m (chromosome mp), the gene fo r 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 specie s.
