[Oligonucleotide-binding proteins of Drosophila: tissue specificity]. / Oligonukleotidsviazyvaiushchie belki Drozofily: tkanevaia spetsifichnost'.

A reaction of native Drosophila proteins with an alkylating oligonucleotide derivative bearing 4-[(N-2-chlorethyl-N-methyl)amino]benzylamine at the 5' terminal phosphate has been investigated. It was found, that the reagent alkylates a few proteins (90, 50, 44, 39, 32 kDa). The modification was organ specific. The labeled 39 kDa protein is present in the ovaries only, while the modified 32 kDa protein is found only in the bulbus.
