Scientific summary

The ASB2 gene encodes two isoforms, a hematopoietic-type ASB2α and a muscle-type ASB2β that are the specificity subunits of E3 ubiquitin ligase complexes involved in differentiation of hematopoietic and muscle cells, respectively. These suggest that ASB2 proteins exert their effect in cell differentiation through the targeting of specific substrates to degradation by the proteasome.

Although ASB2 was identified by our group as induced by retinoic acid in acute promyelocytic leukemia cells, it is specifically expressed in normal immature hematopoietic cells including hematopoietic stem cells and so is likely to be relevant during early hematopoiesis. Importantly, ASB2 is a transcriptional target of three major acute myeloid leukemia oncoproteins that act as transcriptional repressors suggesting that ASB2 repression may participate in the transformation process. We have recently showed that the hematopoietic isoform ASB2α drives polyubiquitylation and proteasome-mediated degradation of the actin-binding protein filamins and can regulate integrin-dependent functions such as adhesion and migration of hematopoietic cells. The data available so far indicate that filamins anchor transmembrane and cytoplasmic signaling proteins involved in motility, adhesion and cell-shape modulation to the actin cytoskeleton, providing cell-soluble factors, cell-cell or cell-extracellular matrix connections. Our working hypothesis is that by targeting filamins to proteasomal degradation, ASB2 proteins may modulate the cross-talk between hematopoietic cells and their microenvironment and thus their cell fate within the bone marrow.

Our general objective is therefore directed to decipher the functional role of ASB2 proteins in hematopoiesis and in myogenesis. We therefore propose the following specific aims: (i) to determine the functions of ASB2α and ASB2β, (ii) to decipher the mechanisms of action of ASB2 proteins through the identification and characterization of their substrates targeted to proteasome degradation. To unravel the role of ASB2 repression in haematological disease development is also one of the major issues of our work. These will contribute to the better understanding of the molecular mechanisms controlling differentiation of hematopoietic and muscle cells.
