MYADM, belonging to the MAL family, is a 322-amino acid protein having 7 hydrophobic transmembrane domains, several potential consensus sites for phosphorylation and sequence homology with the T-cell differentiation protein MAL and plasmolipin. It shares 75.8% sequence identity with mouse in the transmembrane regions and is associated with differentiation of hematopoietic cells or acute promyelocytic leukemia cells. Its expression is up-regulated in NB4 cells induced by all-trans retinoic acid whereas down regulation inhibits colony formation of bone marrow cells. MYADM could serve as a new marker for hematopoietic differentiation and is a target for diagnostic, prognostic and/or therapeutic interventions. It is known to express widely in brain and pancreatic islet cells.
