The product of the resulting BCR -
ABL fusion oncogene possesses ABL's so - called tyrosine kinase activity — the ability to add phosphate chemical groups to the amino acid tyrosine — but fails to turn off appropriately.
This gene encodes for a Bcr -
abl fusion protein.
[11] Since ABL activates a number of cell cycle - controlling proteins and enzymes, the result of the BCR -
Abl fusion is to speed up cell division.
The activity of tyrosine kinases is typically regulated in an auto - inhibitory fashion, but the BCR -
Abl fusion gene codes for a protein that is «always on» or continuously activated leading to unregulated cell division (i.e. cancer).
By analogy to the gag /
abl fusion protein of Abelson murine leukemia virus, the replacement of amino terminal c - abl sequences by bcr sequences in P210 may create a transforming protein involved in CML.
To test whether the P210 is the product of the novel 8.5 - kilobase bcr /
abl fusion transcript, antibodies were prepared against c - abl and bcr determinants.
