High impact information on asrij

• Embryos homozygous for a chromosomal deficiency that removes asrij have no embryonic hemocytes [1].
• Drosophila asrij is expressed in pole cells, trachea and hemocytes [1].
• We have analysed the expression, during embryogenesis, of a Drosophila gene asrij (Sanskrit; asR ij = blood), which encodes a novel conserved protein with putative transmembrane domains. asrij is expressed in the pole cells, amnioserosa, trachea and hemocytes [1].
• Asrij is expressed in the Drosophila lymph gland. It is expressed in the posterior signaling centre, medullary zone and cortical zone differentiated hemocytes [2].
• Asrij is required to maintain the niche cells thereby regulating the prohemocyte population and their differentiation. It regulates Notch signaling required for crystal cell specification [2].
