CD114, also known as CSF3R and GCSFR (Granulocyte Colony Stimulating Factor Receptor), is a cell surface receptor for CSF3 (Colony Stimulating Factor 3) that plays a critical role in the proliferation, differentiation, and activation of hematopoietic cells of the neutrophil lineage. CD114 is a member of the cytokine receptor superfamily and the immunoglobulin (Ig) superfamily that may also function in some other cell surface adhesion or recognition processes. CD114 contains an immunoglobulin (Ig)-like domain, a cytokine receptor-homologous (CRH) domain and three fibronectin type III (FNIII) domains in the extracellular region (ECD). CD114 is expressed in mature neutrophils, neutrophilic precursors, myeloid leukemia cells, and placenta. Binding of its ligand induces dimerization or oligomerization of this receptor and leads to the activation of several intracellular signaling cascades, including the Jak/Stat, PI3/Akt, Ras-Raf-MAP kinase, and Src family kinase (Lyn and Syk) pathways. CD114 thus plays important functional roles in defense against infection, inflammation and repair, and in the maintenance of steady state hematopoiesis. Mutations in this gene are a cause of Kostmann syndrome, also known as severe congenital neutropenia. These mutations typically led to a truncation in the cytoplasmic domain of the G­CSF R leading to maturation arrest of neutrophil precursors in the bone marrow and neutropenia in peripheral blood.
