Products from BPS Bioscience require a minimum order value above 400€
Encompassing Amino Acids: 637-926
Applications: Useful for the study of enzyme kinetics and regulation, to dephosphorylate target substrates and for screening inhibitors.
Assay Conditions: The specific activity was determined using pNPP. Assay conditions: 50 mM HEPES, pH 7.4, 2 mM EDTA, 3 mM DTT, 100 mM NaCl, 20 mM pNPP, and 20 ng/µl enzyme for 5 minutes at 30°C.
Background: PTPs are known to be signaling molecules that regulate a variety of cellular processes including cell growth, differentiation, mitotic cycle, and oncogenic transformation. This protein contains a C-terminal PTP domain and an N-terminal domain homologous to the band 4.1 superfamily of cytoskeletal-associated proteins. This PTP acts at junctions between the membrane and the cytoskeleton and has been shown to interact with glutamate receptor delta 2 and epsilon subunits. It also is thought to play a role in signalling downstream of the glutamate receptors through tyrosine dephosphorylation.
