Role and significance of c-KIT receptor tyrosine kinase in cancer: A review.

c-kit is a classical proto-oncogene that encodes a receptor tyrosine kinase (RTK) that responds to stem cell factor (SCF). C-KIT signaling is a critical regulator of cell proliferation, survival, and migration and is implicated in several physiological processes, including pigmentation, hematopoiesis and gut movement. Accumulating evidence suggests that dysregulated c-KIT function, caused by either overexpression or mutations in c-kit, promotes tumor development and progression in various human cancers.
