MAP Kinase 6 (Mitogen-activated Protein Kinase 6, MAPK 6, MAPK6, PRKM6, Extracellular Signal-regulated Kinase 3, ERK3, ERK-3, HsT17250, MAP Kinase Isoform p97, p97-MAPK, p97MAPK)

ERK3, also known as MAPK6 or p97 MAPK, is almost 50% identical to ERK1/2 at the kinase\ndomain located in its amino-terminal region (1). However, ERK3 is distinguished from other MAP kinases in that it lacks the conserved TXY motif in its activation loop, possessing instead an SEG motif (1,2). Phosphorylation at Ser189 in the SEG motif has been reported (2,3). With limited information about its upstream kinases and downstream substrates, the significance\nof this phosphorylation remains to be elucidated 3,4). ERK3 is an inherently unstable protein, rapidly degraded through amino-terminal ubiquitination and proteasome degradation (3,5). A site-specific cleavage, depending on a short stretch of acidic residues of ERK3, might regulate its translocation from the Golgi/ERGIC to the nucleus during the cell cycle (6). Accumulating evidence suggests that ERK3 is involved in cell differentiation (1,3,6).\n\nApplications: \nSuitable for use in Flow Cytometry, Western Blotting, Immunoprecipitation. Other applications not tested.\n\nRecommended Dilution:\nFlow Cytometry: 1:200\nWestern Blotting: 1:1000\nImmunoprecipitation: 1:50\nOptimal dilutions to be determined by the researcher.\n\nStorage and Stability:\nMay be stored at 4 degrees C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot. Store at -20 degrees C. Aliquots are stable for at least 12 months at -20 degrees C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
