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. [5] G-CSF-R is a cell-surface receptor for the granulocyte colony-stimulating factor (G-CSF). [6] The G-CSF receptors belong 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, [7] and colony-stimulating.
Mutations in this gene are a cause of Kostmann syndrome, also known as severe congenital neutropenia. [8]
Mutations in the intracellular part of this receptor are also associated with certain types of leukemia. [9]
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. [10]
Granulocyte colony-stimulating factor receptor has been shown to interact with Grb2, [11] HCK [12] and SHC1. [11]
