Biological Information

Background Information:

The protein tyrosine phosphatase, non-receptor type 11 (SHP-2) contains two tandem SH2 domain repeats at its N terminus and is expressed widely multiple growth factor receptor and cytokine pathways. Specifically, SHP-2 is thought to activate mitogen-activated protein kinase (MAPK) as the result of its direct action on PDGF and EGF growth factor receptors in response to ligand binding. Upregulation of SHP-2 activity is therefore believed to be a causative factor in vascular inflammation, tumor cell proliferation, and metastasis. More recently, SHP-2 deficiency has been shown to impair insulin sensitivity of glucose metabolism.

Testing Information

Procedure Summary:

Human recombinant phosphatase PTPN11 (SHP-2) expressed in E. coli is used. Test compound and/or vehicle is preincubated with 45 ng/ml enzymeó for 15 minutes at 37°C in modified HEPES buffer pH 7.2. The reaction is initiated by addition of 100 μM DiFMUP for 60 minutes. Determination of the amount of DiFMU formed is read spectrofluorimetrically at 358 nm/450 nm. Compounds are screened at 10 µM.

Substrate:

100 µM DiFMUP

Incubation:

60 min at 37°C

Control Inhibitor:

(NH₄)₆Mo₇O₂₄

Criteria For Significance:

≥ 50% of max stimulation or inhibition

Test Concentration / Dose:

Suggested concentration for initial testing is 10 uM

Test Sample Requirements:

Minimum for 1) Screen: 25 μl of 10 mM stock -OR- 1 mg (pre-weighed). 2) Dose Response: 60 μl of 10 mM stock -OR- 1 mg (pre-weighed).

Minimum Order Quantity:

2
