This antibody is predicted to react with bovine, canine, chicken, mouse, non-human primate and Xenopus based on 100% sequence homology. This antibody is specific for the ~45 kDa MEK 1 protein phosphorylated at Thr386 in Western blots of human brain extracts.

MEK 1 (MAP Kinase Kinase, also known as MKK) is an integral component of the MAP kinase cascade that regulates cell growth and differentiation (Ahn, 1993;Chong et al., 2003). This pathway also plays a key role in synaptic plasticity in the brain (Adamsand Sweatt, 2002). Activated MEK 1 acts as a dual specificity kinase phosphorylating both a threonine and a tyrosine residue on MAP kinase (Kyriakis et al., 1991; Seger et al., 1991; Crews et al., 1992). Conversely there also appears to be a feedback phosphorylation of MEK 1 by MAP kinase. The sites on MEK 1 that are phosphorylated by MAP kinase are Thr292 and Thr386 (Mansour et al., 1994).
