Fragment
Fab fragment
Post Translational Modifications
Oxidized on Cys-215; the Cys-SOH formed in response to redox signaling reacts with the alpha-amido of the following residue to form a sulfenamide cross-link, triggering a conformational change that inhibits substrate binding and activity. The active site can be restored by reduction. Ser-50 is the major site of phosphorylation as compared to Ser-242 and Ser-243. Activated by phosphorylation at Ser-50. S-nitrosylation of Cys-215 inactivates the enzyme activity. Sulfhydration at Cys-215 following endoplasmic reticulum stress inactivates the enzyme activity, promoting EIF2AK3/PERK activity.
Subunit Structure
Interacts with EPHA3 (phosphorylated); dephosphorylates EPHA3 and may regulate its trafficking and function. Interacts with MET.
Similarity
Belongs to the protein-tyrosine phosphatase family. Non-receptor class 1 subfamily.
Subcellular Location
Endoplasmic reticulum membrane>Peripheral membrane protein>Cytoplasmic side.
Note: Interacts with EPHA3 at the cell membrane.
Note: Interacts with EPHA3 at the cell membrane.
Preparation and Storage
Store at -20 degree C. Stable for 12 months from date of receipt.

Related Product Information for anti-PTP1B antibody
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.

Product Notes
The PTP1B ptpn1 (Catalog #AAA329831) is an Antibody produced from Rabbit and is intended for research purposes only. The product is available for immediate purchase. The Phospho-PTP1B (Tyr66) Antibody reacts with Human, Mouse, Rat Predicted Reactivity: Pig (100%), Bovine (100%), Horse (100%), Sheep (100%), Rabbit (100%), Dog (100%), Xenopus (86%) and may cross-react with other species as described in the data sheet. AAA Biotech's PTP1B can be used in a range of immunoassay formats including, but not limited to, ELISA (Peptide ELISA), ICC (Immunocytochemistry), IF (Immunofluorescence), WB (Western Blot). Researchers should empirically determine the suitability of the PTP1B ptpn1 for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "PTP1B, Polyclonal Antibody" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
