CD116, also known as GM-CSFRα (granulocyte macrophage colony stimulating factor receptor alpha), is a component of the receptor complex that mediates cellular responses to GM­CSF. This receptor complex is composed of a cytokine-specific alpha- chain CD116 and a beta-chain CD131 shared with the receptors for IL-3 and IL-5. CD116 alone binds GM-CSF with low affinity, whereas CD131 does not bind GM-CSF by itself. Association with CD131 converts CD116 from a low affinity to a high affinity receptor for GM­CSF. GM­CSF is a hematopoietic cytokine that regulates differentiation, survival, and proliferation of colony-forming unit-granulocyte-macrophage progenitor cells. It promotes the differentiation and mobilization of granulocyte­macrophage, erythroid, megakaryocyte, and eosinophil progenitors. GM­CSF also enhances the activation of myeloid cell effector functions and plays an important role in the development of Th1 biased immune responses, allergic inflammation, and autoimmunity. CD116 is a single pass, type I transmembrane glycoprotein that consists of a 298 amino acid (aa) extracellular region with 2 fibronectin type III (FN3) domains and a juxtamembrane WSXWS motif, a transmembrane domain, and a 54 aa cytoplasmic tail that mediates the activation of Janus kinase (Jak)- Stat and MAPK as well as phosphatidylinositol 3-kinase (PI3K) pathways.  CD116 is expressed on hematopoietic stem cells, progenitor and differentiated cells in the myeloid lineage, vascular endothelial cells, and placenta as well as in those non­hematopoietic tumor cells.  Soluble forms of CD116 retain the ability to bind GM­CSF.

Primers: Gene insert coding sequence can be confirmed by following primers:

(a) forward (or 5'-end) primer: 5’-CAAATGGGCGGTAGGCGTG-3’;

(b) reverse (or 3'-end) primer: 5’-CCAGGTTTCCGGGCCCTCAC-3’

 

 

Note: The sequence may vary due to the naturally occurring variants or mutations, such as single nucleotide polymorphism, or the artifact during PCR amplification.  High fidelity PCR systems should always be used.
