Issaouane Erg confined to basins. Sand in the Issaouane Erg, below the level of the sand dunes, has accumulated to a depth of 20 to 30 meters. It has barchan dunes as well as star dunes of 300 to 430 meters high. The presence of both barchan dunes (which form due to unidirectional winds) and star dunes (which form when winds from various directions deposit sand) "suggests that wind regimes have changed over time". NASA's "Earth Observatory" notes all three types of erg dunes are present in the photos of the Issaouane Erg taken from the International Space Station: stationary mega dunes,
ERG (gene) Sarcoma cases have an EWS1-ERG fusion. In acute myeloid leukemia, the t(16;21) translocation in myeloid leukemia fuses TLS/FUS to ERG which disrupts the natural TLS/FUS RNA binding domain, and instead inserting the ERG DNA binding domain. "ERG" is located on chromosome 21. The ERG protein is expressed at a similar level throughout the body. "ERG" has been shown to interact with: ERG (gene) ERG (ETS-related gene) is an oncogene. ERG is a member of the ETS (erythroblast transformation-specific) family of transcription factors. The "ERG" gene encodes for a protein, also called ERG, that functions as a transcriptional regulator. Genes in
