The complete nucleotide sequence of human abl RNA containing exon Ia was determined. It spans 5598 nucleotides and codes for a protein of 1130 amino acids. The 3' untranslated region contains two short open reading frames and multiple ATTT(A) motifs characteristic of short lived mRNAs. Computer analysis of the abl protein predicts four domains distinct with regard to surface probability and chain flexibility. Nucleotide analysis of the abl segment within a bcr-abl cDNA cloned from the K562 cell line indicated no further alterations within the coding region. A bcr-abl construct containing this segment transformed, together with c-myc, RAT-1 cells and produced a highly active tyrosine kinase.
