Abstract
In mammalian cells, a family of mitochondrial transcription termination factors (MTERFs) regulates mitochondrial gene expression. Mitochondrial transcription termination factor 3 (MTERF3) is the most conserved member of the MTERF family and a negative regulator of mammalian mitochondrial DNA transcription. To create a specific polyclonal antibody against human MTERF3 (hMTERF3), we first cloned hMTERF3 into prokaryotic expression vector pGEX-4T-1, and GST-hMTERF3 was efficiently expressed in Escherichia coli after induction by IPTG. The expressed GST-tagged hMTERF3 fusion protein was purified by passive electro-elution process and then used to immunize BALB/c mice, we obtained anti-GST-hMTERF3 polyclonal antibody purified by protein A column and determined the sensitivity and specificity of the antibody against human MTERF3 by enzyme-linked immunosorbent assay and Western blot assay. Furthermore, the full-length hMTERF3 protein expressed in human embryonic kidney 293T cells was detected by anti-GST-hMTERF3 in western blot analysis and immunofluorescence staining. Taken together, our results demonstrate the functionality of the mouse anti-GST-hMTERF3 polyclonal antibody which will provide a useful tool for further characterization of hMTERF3.
