EhGEF was cloned in amoebic expression vector pEhHYG-tetR-O- CAT by replacing CAT gene with the gene of interest in the cassette using double digestion by KpnI and BamHI either in sense or antisense orientations. EhGEF was cloned into pEh-Neo-GFP vector under Xho1 and BamH1 sites so that GFP comes at N-terminus of protein. HA-tagged GEF was cloned in pEh-Neo-3HA vector under SmaI and XhoI sites. The ΔEhGEF was generated by introducing stop codon at 121 position (Alanine to stop codon) by site directed mutagenesis.
