[A method for detecting protein-protein interactions. Detection of proteins with the molecular weight of approximately 37 kD binding with tryptophanyl-tRNA-synthetase].
A procedure for detecting protein-protein interactions is proposed. It is based on blotting of electrophoretically separated protein mixtures followed by detection of the proteins interacting with a given 125I-labelled protein used as a probe. Application of this approach to lysates of cultured mammalian cells enabled us to reveal a unique 37 kDa polypeptide interacting with 125I-labelled bovine tryptophanyl-tRNA synthetase (EC 6.1.1.2).
