KIT (also known as CD117 antigen):KIT is a gene that encodes a protein functioning as a receptor tyrosine kinase, essential for cell growth, differentiation, and survival. It plays a crucial role in the development and function of various cell types, including melanocytes, germ cells, and hematopoietic cells. Understanding KIT signaling pathways may offer insights into targeted treatments for cancers and other diseases involving abnormal KIT activity.
