Cluster of differentiation 117 (CD117), also known as KIT or c-Kit, is a member of the type III receptor tyrosine kinase family. This recombinant non-human primate Rhesus macaque CD117 protein dimer (CSP-25194-03) is a cis-homodimer (cis-dimer) and contains a CD117 extracellular domain (UniProt# F6V858, amino acids Ser25-Pro524) fused with a proprietary cis-dimer motif followed by a tandem His-Avi tag at the C-terminus. This dimeric protein is expressed in HEK293T cells. The recombinant Rhesus macaque CD117 protein dimer is bioactive and can bind to stem cell factor (SCF). It also binds CD117-specific antibodies. This CD117 protein dimer can be used as an antigen for in vitro assays and antibody screening, and as an immunogen for immunization to generate antibodies targeting more conformational epitopes.

Background
Cluster of differentiation 117 (CD117), is a member of the type III receptor tyrosine kinase family. CD117 is also known as KIT, C-Kit, mast/stem cell growth factor receptor (SCFR), KIT proto-oncogene receptor tyrosine kinase, and MASTC. CD117 contains an extracellular domain with five immunoglobulin-like loops, a transmembrane domain, a juxtamembrane domain, and an intracellular domain. CD117 is a Type 1 transmembrane protein, expressed on hematopoietic stem cells, mast cells, melanocytes, germ cells, and interstitial cells of Cajal. CD117 exists as a monomer under normal physical conditions. Upon binding to its natural ligand, stem cell factor (SCF), homodimerization occurs between two CD117 monomers; this homodimerization is essential for its activation. However, oncogenic mutations can cause ligand-independent pathological dimerization and constitutive activation. CD117 is frequently overexpressed or dysregulated in human cancers, including gastrointestinal stromal tumors, acute myeloid leukemia, melanoma, and small cell lung cancer. CD117 is a promising drug target, especially in precision oncology and regenerative medicine. The CD117 protein is highly homologous between non-human primates (NHPs) and humans. Understanding CD117 dimerization and its activation is crucial for developing targeted therapeutics.
