Rabbit Anti-MAPK6/FITC Conjugated antibody
background:
Mitogen-activated protein kinase (MAPK) signaling pathways involve closely related MAP kinases, including extracellular-signal-related kinase 3 (ERK 3, also designated PRKM6 and p97MAPK). Serum, growth factors and phorbol esters can initiate ERK 3 signaling pathways. Despite lacking a definitive nuclear localization sequence, ERK 3 constitutively localizes to the nucleus upon activation. p38 pathway activation-dependent upregulation of ERK 3 is independent of the status of p53, Bcl-2 and caspase-3 during cell stress and damage induced by proteasome inhibition, suggesting ERK 3 in part mediates intracellular defense or cell rescue. The human ERK 3 gene maps to chromosome 15q21.2 and encodes a 721 amino acid protein.
Function:
Phosphorylates microtubule-associated protein 2 (MAP2). May promote entry in the cell cycle.
Subunit:
Heterodimer with ERK4/MAPK4. Interacts with (via FRIEDE motif) MAPKAPK5 (By similarity). Interacts with UBE3A; this interaction may be indirect and mediated by HERC2, possibly via HERC2 interaction with NEURL4.
Subcellular Location:
Cytoplasm (By similarity). Nucleus (By similarity). Note=Translocates to the cytoplasm following interaction with MAPKAPK5 (By similarity).
Tissue Specificity:
Highest expression in the skeletal muscle, followed by the brain. Also found in heart, placenta, lung, liver, pancreas, kidney and skin fibroblasts.
Post-translational modifications:
Dually phosphorylated on Thr-626 and Tyr-628, which activates the enzyme.
Similarity:
Belongs to the protein kinase superfamily. CMGC Ser/Thr protein kinase family.
MAP kinase subfamily.
Contains 1 protein kinase domain.
