Anti-MAP3K15 antibodies are used in the immunodetection of the protein mitogen-activated protein kinase kinase kinase 15. In humans, the canonical protein has a reported length of 1313 amino acid residues and a mass of 147.4 kDa. Up to 3 different isoforms have been reported for this protein. A member of the STE Ser/Thr protein kinase protein family, MAP3K15 is believed to function in a signal transduction pathway that is activated by various cell stresses and leads to apoptosis. Synonyms for this target antigen include MEK kinase 15, MEKK 15, apoptosis signal-regulating kinase 3, and MAPK/ERK kinase kinase 15. MAP3K15 gene orthologs have been reported in the mouse, rat, bovine, frog, zebrafish, chimpanzee and chicken species. Western Blot is a widely used application for the MAP3K15 antibodies listed below. In addition, ELISA is also a common application.
