Anti-SMIM4 antibodies enable researchers to detect and measure the SMIM4 antigen in biological samples. This target is a reported synonym of the UQCC5 gene, which encodes ubiquinol-cytochrome c reductase complex assembly factor 5. This protein is known to be required for the assembly and stability of the mitochondrial ubiquinol-cytochrome c reductase complex (complex III (CIII) or cytochrome b-c1 complex), a multisubunit transmembrane complex that is part of the mitochondrial electron transport chain (ETC) which drives oxidative phosphorylation (By similarity). The human version of SMIM4 has a canonical amino acid length of 70 residues and a protein mass of 8.7 kilodaltons. It is reported to be localized in the mitochondria of cells. SMIM4 is a member of the UQCC5 protein family. Immunocytochemistry is the most common application for the SMIM4 antibodies listed below. Western Blot, Immunofluorescence, and Immunohistochemistry are also common applications.
