NCIt definition : An orally bioavailable class 1 and 2 inhibitor of the serine/threonine-protein kinase
B-raf (BRAF) protein, with potential antineoplastic activity. Upon oral administration,
BRAF inhibitor PF-07799933 selectively binds to and inhibits the activity of class
1 and 2 BRAF alterations. This inhibits the proliferation of tumor cells which express
these BRAF alterations. BRAF, a member of the raf family of serine/threonine protein
kinases, plays a role in the regulation of mitogen-activated protein kinase (MAPK)
and extracellular signal-regulated kinase (ERK) signaling pathways, which may be constitutively
activated due to BRAF gene mutations. Mutated forms and fusions of BRAF are associated
with a number of neoplastic diseases.;
