A point mutation is responsible for the acquisition of transforming properties by the T24 human bladder carcinoma oncogene

Nature. 1982 Nov 11;300(5888):149-52. doi: 10.1038/300149a0.


The genetic change that leads to the activation of the oncogene in T24 human bladder carcinoma cells is shown to be a single point mutation of guanosine into thymidine. This substitution results in the incorporation of valine instead of glycine as the twelfth amino acid residue of the T24 oncogene-encoded p21 protein. Thus, a single amino acid substitution appears to be sufficient to confer transforming properties on the gene product of the T24 human bladder carcinoma oncogene.
