Erg (landform) when liquid methane rained and eroded the ice bedrock, possibly in the form of flash floods. Alternatively, the sand could also have come from organic solids produced by photochemical reactions in Titan's atmosphere. Erg (landform) An erg (also sand sea or dune sea, or sand sheet if it lacks dunes) is a broad, flat area of desert covered with wind-swept sand with little or no vegetative cover. The term takes its name from the Arabic word "ʿarq" (), meaning "dune field". Strictly speaking, an erg is defined as a desert area that contains more than of aeolian or wind-blown sand
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
