Background: CD117/c-kit

Stem cell factor receptor (SCF R), also known as c-Kit and CD117, is a type III receptor tyrosine kinase that acts as the receptor for the cytokine SCF (1, 2). Mature human SCF R consists of an extracellular domain (ECD) with five tandem immunoglobulin-like domains, a single transmembrane segment, and a cytoplasmic region with a split tyrosine kinase domain. Within the ECD, human SCF R shares 73% and 76% amino acid sequence identity with mouse and rat SCF R, respectively. At least 4 SCF R isoforms, produced by alternative mRNA splicing, have been identified in humans and 2 are characterized by the presence or absence of a tetrapeptide sequence (GNNK) in the juxtamembrane region of the ECD (3, 4). Human SCF R is expressed in embryonic stem cells and is involved in regulation of cell survival and proliferation, hematopoiesis, gametogenesis, and melanogenesis (1, 2, 5, 6). SCF R interacts with noncovalent dimers of transmembrane or soluble SCF to trigger receptor dimerization and initiate signaling (7). Our Avi-tag Biotinylated rhSCF R features biotinylation at a single site contained within the Avi-tag, a unique 15 amino acid peptide. Protein orientation will be uniform when bound to streptavidin-coated surface due to the precise control of biotinylation and the rest of the protein is unchanged so there is no interference in the protein's bioactivity.
