Receptor for granulocyte colony-stimulating factor (CSF3), essential for granulocytic maturation. Plays a crucial role in the proliferation, differentiation and survival of cells along the neutrophilic lineage. In addition it may function in some adhesion or recognition events at the cell surface

Homodimer. The dimeric receptor binds two CSF3 molecules. Interacts with CEACAM1; down-regulates the CSF3R-STAT3 pathway through recruitment of PTPN6 that dephosphorylates CSF3R (By similarity)

One or several isoforms have been found in myelogenous leukemia cell line KG-1, leukemia U-937 cell line, in bone marrow cells, placenta, and peripheral blood granulocytes. Isoform GCSFR-2 is found only in leukemia U-937 cells. Isoform GCSFR-3 is highly expressed in placenta

The WSXWS motif appears to be necessary for proper protein folding and thereby efficient intracellular transport and cell-surface receptor binding

The box 1 motif is required for JAK interaction and/or activation

• Hereditary neutrophilia (NEUTROPHILIA)

  A form of lifelong, persistent neutrophilia, a condition characterized by an increase in the number of neutrophils in the blood.

• Neutropenia, severe congenital 7, autosomal recessive (SCN7)

  A form of severe congenital neutropenia, a disorder of hematopoiesis characterized by maturation arrest of granulopoiesis at the level of promyelocytes with peripheral blood absolute neutrophil counts below 0.5 x 10(9)/l and early onset of severe bacterial infections.
