Issaouane Erg Issaouane Erg The Issaouane Erg (also called Issaouane-N-Irrararene) is an approximately 38,000 km erg (sand sea) in Algeria's portion of the Sahara desert, located at . The Issaouane Erg is located near the Ahaggar Mountains. It is part of a major dune field that extends from Issaouane Erg in the north to the Sudanese Erg in the south, flanked by the Libyan erg of Murzuq. In the north, the Issaouane Erg ends at the Tinrhert Plateau and in the south at the Fadnoun Plateau. To a large extent it follows the 500-m contour of the surrounding landscape, ergs mostly being
ERG (gene) in mature lymphocytes (types of white blood cells). Therefore, ERG may act as a regulator of differentiation of early hematopoietic cells. The Mld2 mutation, generated through an ENU mutagenesis screen, was the first non-functional allele of "Erg". Homozygous Mld2 is embryonic lethal at day 13.5. Adult mice heterozygous for the Mld2 mutation have hematopoietic stem cell defects. This means that when the ERG gene was not actively transcribed and the ERG protein produced, a mouse's hematopoietic cells were unable to function properly. Since ERG is important to the ability of the hematopoietic cells to function and self-renew, there may be
