Anti-MAPKKKK5 antibodies enable researchers to detect and measure the MAPKKKK5 antigen in biological samples. This target is a reported synonym of the MAP4K5 gene, which encodes mitogen-activated protein kinase kinase kinase kinase 5. This protein is known to function in intracellular signal transduction and protein phosphorylation, among other biological roles. The human version of MAPKKKK5 has a canonical amino acid length of 846 residues and a protein mass of 95 kilodaltons. It is reported to be localized in the cytoplasm of cells. Other names for this target antigen include GCKR, KHS, and KHS1. Immunohistochemistry is the most common application for the MAPKKKK5 antibodies listed below. ELISA and Western Blot are also common applications.
