The structural elements of Bcr-Abl oncoprotein (p210BCR-ABL) isoforms, b2a2 and b3a2, expressed in Chronic Myelogenous Leukemia (CML), were predicted by Psipred and ExPASy servers. These proteins are tyrosine kinases with masses of 210-kDa. Structural differences were found in five -helices (25, ', 26, 27 and 29) and nine β-strands (β12, β13, β15, β', β17, β30, β", β34 and β35). These differences are present in the SH3, SH2, SH1 and DNA-binding domains. The structural differences might be able to explain the different roles played by the two isoforms in mediating signal transduction during the development of CML
