PP2 has been used:
  • to analyze the effects of Src/focal adhesion kinase (FAK) signaling on IQ domain GTPase-activating protein 1 (IQGAP1)-mediated anoikis resistance
  • for Src inhibition to study its effect on epidermal growth factor receptor (EGFR) and nuclear factor erythroid 2-related factor 2 (Nrf2) phosphorylation in non-small cell lung cancer (NSCLC) cells
  • for pharmacological inhibition of SRC in MDA-MB-231 breast cancer cells

Biochem/physiol Actions

PP2 is a selective inhibitor of Src-family tyrosine kinases of non-receptor tyrosine kinases (nRTK). It shows >10,000-fold selectivity over Zeta-chain-associated protein kinase 70 (ZAP-70) and Janus kinase 2 (JAK2). PP2 effectively reduces cervical cancer proliferation in vitro and in vivo.

Studies have demonstrated that the solute carrier family 11 member 1 (SLC11A1) is heavily glycosylated and phosphorylated in macrophages. However, the mechanisms of SLC11A1 phosphorylation, and the effects of phosphorylation on SLC11A1 activity remain largely unknown. Here, the tyrosine phosphorylation
