Construction of SV40 deletion mutants and delimitation of the binding domain for heat shock protein to the amino terminus of large T-antigen.

Abstract excerpt

SV40 large T-antigen (T-ag) mutants were generated using a cassette mutagenesis strategy and naturally occurring restriction sites. T-ag mutant constructs included internal in-frame deletions, frame-shift deletions that resulted in amino-terminal fragments, and internal initiation mutants that produced carboxy-terminal fragments; no foreign amino acids were introduced. The deletion mutants were stably expressed...
