The granulocyte colony-stimulating factor receptor (G-CSF-R) also known as CD114 (Cluster of Differentiation 114) is a protein that in humans is encoded by the CSF3R gene.[1] G-CSF-R is a cell-surface receptor for the granulocyte colony-stimulating factor (G-CSF).[2] The G-CSF receptors belongs to a family of cytokine receptors known as the hematopoietin receptor family. The granulocyte colony-stimulating factor receptor is present on precursor cells in the bone marrow, and, in response to stimulation by G-CSF, initiates cell proliferation and differentiation into mature neutrophilic granulocytes and macrophages.

The G-CSF-R is a transmembrane receptor that consists of an extracellular ligand-binding portion, a transmembrane domain, and the cytoplasmic portion that is responsible for signal transduction. GCSF-R ligand-binding is associated with dimerization of the receptor and signal transduction through proteins including Jak, Lyn, STAT, and Erk1/2.


The class IV isoform defective for both internalization and differentiation signaling.[3]

Clinical significance

Mutations in this gene are a cause of Kostmann syndrome, also known as severe congenital neutropenia.[4]

Mutations in the intracellular part of this receptor are also associated with certain types of leukemia.[5]

In clinical medicine, there is a suggestion that use of GCSF should be avoided, at least in children and adolescents and perhaps adults, when G-CSFR isoform IV is overexpressed.[6]


Granulocyte colony-stimulating factor receptor has been shown to interact with Grb2,[7] HCK[8] and SHC1.[7]
