The recognition of new Y-chromosome markers represents a major leap in the investigation of human genetic diversity (in male lineages, complementing the information from female lineages derived from mitochondrial DNA). The resulting phylogeny supports the out-of-Africa origins of our species and opens the way to further insights into prehistoric demography and world prehistory.
The Mep ammonium transporters of Saccharomyces cerevisiae share amino acid sequence identity with the Rh blood group antigen proteins. A new study shows that the Rhg glycoproteins transport ammonium when heterologously expressed in mep mutant yeast cells, indicating a role for the Rh antigen complex.
