Abstract:
:A p60K protein in human colon adenocarcinoma tumor cell lines was identified as a myristoylated pp60c-src by fluorography and radioimmunoprecipitation analysis. Prevention of the myristoylation of pp60c-src was determined with N-fatty acyl glycinal compounds. Of the compounds tested, N-myristoyl glycinal diethylacetal, N-lauroyl glycinal diethylacetal, N-myristoyl glycyl glycinal diethylacetal, and N-myristoyl-4-aminobutyl-aldehyde diethylacetal strongly blocked the myristoylation, but N-decanoyl glycinal diethylacetal and N-palmitoyl glycinal diethylacetal did not. The myristoyl blocking compounds depressed colony formation, cell proliferation, and specific localization to the plasma membrane of pp60c-src. The results taken together suggest that myristoylation of the c-src oncogene product may be very important for tumorigenicity of c-src gene expressed cells.
