High impact information on TSPAN32

  • Phemx maps to the distal region of chromosome 7, a segment of the mouse genome that contains a cluster of genes that exhibit genomic imprinting [1].
  • The human PHEMX ortholog is specifically expressed in hematopoietic organs and tissues and, in contrast to murine Phemx, undergoes alternative splicing [1].
  • Conceptual translation of the murine Phemx cDNA predicts a 25-kDa polypeptide with four hydrophobic regions and several potential phosphorylation sites, suggestive of a transmembrane protein involved in cell signaling [1].
  • Phemx (Pan hematopoietic expression) is a novel murine gene expressed in developmentally regulated sites of hematopoiesis from early in embryogenesis through adulthood [1].
  • Using 5'-RACE and cDNA library screening, we identified an additional 5' sequence for both the murine Tssc6 cDNA and its human homologue TSSC6 [2].
