Storage ：Antibody store in 10 mM PBS, 0.5mg/ml BSA, 50% glycerol. Shipped at 4°C. Store at-20°C or -80°C. Products are valid for one natural year of receipt.Avoid repeated freeze / thaw cycles.

WB Positive detected ：HepG2 cells 

Function ： Tyrosine-protein phosphatase which acts as a regulator of endoplasmic reticulum unfolded protein response. Mediates dephosphorylation of EIF2AK3/PERK,inactivating the protein kinase activity of EIF2AK3/PERK. May play an important role in CKII- and p60c-src-induced signal transduction cascades. May regulate the EFNA5-EPHA3 signaling pathway which modulates cell reorganization and cell-cell repulsion. May also regulate the hepatocyte growth factor receptor signaling pathway through dephosphorylation of MET..

Tissue specificity ：Expressed in keratinocytes (at protein level)..

Subcellular locationi ：Endoplasmic reticulum membrane,Peripheral membrane protein,Cytoplasmic side.

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 1% w/v BSA, 1X TBST at 4°C overnight.
