Transcription profiling of SrcR388A/Y527F or SrcD386N/Y527F stably transfected SYF cells serum-starved overnight and then treated with imidazole 5 mM for 1 h or 12 reveals that the protein tyrosine kinase Src R388A mutant can be rescued in live cells using the small molecule imidazole


ABSTRACT: SrcR388A/Y527F or SrcD386N/Y527F stably transfected SYF cells were serum-starved overnight and then treated with imidazole 5 mM for 1 h or 12 h. RNeasy Miniprep column (Qiagen) was used to prepare total RNA from each treatment group. All samples were run in commercial arrays from Affymetrix,

The restoration of catalytic activity to mutant enzymes by small molecules is well established for in vitro systems. Here, we show that the protein tyrosine kinase Src arginine-388-->alanine (R388A) mutant can be rescued in live cells with the use of the small molecule imidazole. Cellular rescue of a viral Src homolog was rapid and reversible and conferred predicted oncogenic properties. Using chemical rescue in combination with mass spectrometry, we confirmed six known Src kinase substrates and  ...[more]
