STEP (striatum-enriched phosphatase) is a neural-specific protein-tyrosine phosphatase, first isolated from the rat brain.
The 537aa predicted human protein as isolated from cDNA sequences is between 85 and 90% identical to the mouse and rat sequences.
In rat neuronal cell cultures, glutamate-mediated activation of N-methyl-D-aspartate (NMDA) receptors leads to the rapid but transient phosphorylation of extracellular signal-related kinase-2 (ERK2).
NMDA-mediated influx of calcium, activates the calcium-dependent phosphatase calcineurin and the resulting dephosphorylation and activation of STEP.
STEP then inactivatea ERK2 through tyrosine dephosphorylation and blocks translocation of the kinase to the nucleus.
STEP plays a significant role in regulating the ERK activation and downstream signaling in neurons.
Applications:Suitable for use in Western Blot.
Other applications not tested.
Recommended Dilution:Optimal dilutions to be determined by the researcher.
