Western blotting (0.5-4 ug/ml). However, the optimal concentrations should be determined individually. The antibody recognizes 92 kDa MLK3 of human, mouse, and rat origins. It does not cross-react with MLK1, MLK2 and other mixed lineage kinases.
93 kDa. Disclaimer note: The observed molecular weight of the protein may vary from the listed predicted molecular weight due to post translational modifications, post translation cleavages, relative charges, and other experimental factors.
Mixed lineage kinase-3 (MLK-3) is a mitogen-activated kinase kinase kinase that mediates stress-activating protein kinase (SAPK)/c-Jun NH2-terminal kinase activation. MLK-3 and other MLK family kinases are characterized by the presence of multiple protein-protein interaction domains including a tandem leucine/isoleucine zipper (LZs) motif. Leucine zippers are known to mediate protein dimerization raising the possibility that the tandem leucine/isoleucine zippers may function as a dimerization motif of MLK-3 (1). MLK-3 has several interesting structural features including an SH3 domain in the absence of an SH2 domain, a region containing two leucine zippers with an adjacent carboxy-terminal basic region, and a proline rich region. (2). HPK1 has been found to phosphorylate MLK-3 activation loop in vitro, and Ser281 was found to be the major phosphorylation site, indicating that HPK1 also activates MLK-3 via phosphorylation of the kinase activation loop (3).
