Chromosomal Location of MN Blood Group Locus

Chromosomal location of MN blood group locus.

Comparison of human MM, NN, and MN blood group antigens.

Types MM, NN, and MN blood group substances have been isolated. All three materials are glycoproteins containing about 24 % iV-acetyhreuraminic acid, 10 % galactosamine, 5% glucosamine, and 14% galactose. The hexosamines appear to be N-acetylated. Amino acid analysis of the glycoproteins reveals them to be similar in composition and to be especially rich in serine and threonine. Treatment of th...

Oncogenic Myc translocations are independent of chromosomal location and orientation of the immunoglobulin heavy chain locus.

Many tumors are characterized by recurrent translocations between a tissue-specific gene and a proto-oncogene. The juxtaposition of the Ig heavy chain gene and Myc in Burkitt's lymphoma and in murine plasmacytoma is a classic example. Regulatory elements within the heavy chain constant region locus are required for Myc translocation and/or deregulation. However, many genes are regulated by cis-...

Chromosomal location of the tolG locus for tolerance to bacteriocin JF246 in Escherichia coli K-12.

The tolG gene is located between pyrD and fabA on the Escherichia coli chromosome.
