Listed are ELISA Kits for the detection of MEKKK3, an alias name of mitogen-activated protein kinase kinase kinase kinase 3. The human protein, encoded by the gene MAP4K3, is 894 amino acid residues long and has a mass of 101,316 daltons. However, there are up to 3 reported isoforms. It is an enzyme of the non-specific serine/threonine protein kinase class and is a member of the Protein kinase superfamily, STE Ser/Thr protein kinase family, STE20 subfamily. This target may also be known as: MAPK/ERK kinase kinase kinase 3, MEK kinase kinase 3, germinal center kinase-like kinase, germinal center kinase-related protein kinase, MAPKKKK3, MEKKK 3, and MEKKK3.
