Effect of JLP and GID-JLP on Gα12QL-mediated foci formation. Parental NIH3T3 cells were transfected with empty vector pcDNA3 (VC), Gα12QL, full-length JLP (FL-JLP), Gα12QL + FL-JLP, GID-JLP, Gα12QL + GID-JLP, or Gα12QL + GID-JLP + FL-JLP using the calcium phosphate transfection method. (A) The representative foci formed at 14 days were stained photographed (4x). Results presented are from a typical experiment (n = 4). (B) The foci formed from four independent experiments were scored and plotted (mean ± SD).
