The two sets of KIT ectodomains and SCF molecules resemble an upside down ‘‘A’’ letter and the entire ectodomain of KIT is composed of five Ig-like domains: D1-D5. SCF dimer interacts symmetrically with D1, D2, and D3 of two corresponding KIT ectodomains. In addition, KIT ectodomains form homophylic interactions through lateral contacts between D4 and D5 of the two neighboring receptors. The folding of the 5 KIT domains is a typical folding to the immunoglobulin super family. | The two sets of KIT ectodomains and SCF molecules resemble an upside down ‘‘A’’ letter and the entire ectodomain of KIT is composed of five Ig-like domains: D1-D5.
