Nucleotide sequence changes in polyoma ts-a mutants: correlation with protein structure.

AUTOR(ES)
RESUMO

The mutations in three polyoma ts-a mutants have been determined. Two mutants, ts-25 and ts-52, have different single-base changes at the same position (2883) in the early region corresponding to a conserved glycine residue very near the C-terminus of the polyoma large T antigen. Mutant ts-48 has a single-base change at position 2341, as well as a second change at position 1228, in the region of large T antigen shared with medium T antigen.
