The KRAS-G12C inhibitor: activity and resistance - Nature

WebSHP2 generally exhibits an auto-inhibitory conformation, wherein the N-SH2 domain binds to the PTP domain and blocks the catalytic activity. The binding of pY-peptide or RTKs to the N-SH2 domain of SHP2 disrupts N-SH2 binding with the PTP domain and makes the PTP catalytic site available for binding with substrates [ 2 ].
