    Specificity / Sensitivity

    SEK1/MKK4 Antibody detects endogenous levels of total SEK1/MKK4 protein. This antibody does not cross-react with MEK1, MEK2 or MKK3.

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding the N-terminus of human SEK1/MKK4. Antibodies are purified by protein A and peptide affinity chromatography.

    Western Blotting

    Western Blotting

    Western blot analysis of extracts from HEK293, NIH/3T3, C6, COS and A431 cells, using SEK1/MKK4 Antibody.

    Background

    SAPK/Erk kinase (SEK1), also known as MKK4 or Jun kinase kinase (JNKK), activates the MAP kinase homologues SAPK and JNK in response to various cellular stresses and inflamatory cytokines (1-3). Activation of SEK1 occurs through MEKK phosphorylation of serine and threonine residues at positions 257 and 261, respectively. Like MEK, SEK is a dual-specificity protein kinase that phosphorylates SAPK/JNK at a conserved T*PY* site in its activation loop (4). Phosphorylation by Akt at Ser80 inhibits SEK1 and suppresses stress-activated signal transduction (5).
