NCIt definition : A focal adhesion kinase-1 (FAK) inhibitor with potential antiangiogenic and antineoplastic
activities. FAK inhibitor GSK2256098 inhibits FAK, which may prevent the integrin-mediated
activation of several downstream signal transduction pathways, including ERK, JNK/MAPK
and PI3K/Akt, thereby inhibiting tumor cell migration, proliferation and survival,
and tumor angiogenesis. The tyrosine kinase FAK is normally activated by binding to
integrins in the extracellular matrix (ECM) but may be upregulated and constitutively
activated in various tumor cell types.;
