GCSF Receptor / G-CSFR Protein

GCSF Receptor / G-CSFR Protein Overview

GCSF Receptor / G-CSFR reagents

Granulocyte colony-stimulating factor or CSF3 (138970), is a glycoprotein of MW 20,000-25,000 Da that is produced by macrophages stimulated with endotoxin. It plays an important role in granulopoiesis during the inflammatory process. CSF3 exerts its biologic effects through interaction with specific cell surface receptors. Binding studies with radiolabeled CSF3 indicated that CSF3 receptor is expressed not only by progenitor and mature neutrophilic granulocytes, but also by nonhematopoietic cells such as placental cells, endothelial cells, and various carcinoma cell lines. Fukunaga et al. (1990) cloned and characterized cDNAs for human CSF3 receptor. They found that it is abundantly expressed in the human placenta. The receptor contains 813 amino acids and shows marked homology (62.5%) with its murine counterpart. It was found to consist of extracellular, transmembrane, and cytoplasmic domains. Two other classes of the human CSF3 receptor were identified, one of which had a deletion of the transmembrane domain and seemed to represent a secreted, soluble receptor. The third class contained a 27-amino acid insertion in the cytoplasmic domain and was highly expressed in the placenta. Seto et al. (1992) found that CSF3R is subdivided into several regions: an Ig-like domain, a cytokine receptor homologous domain, 3 fibronectin type III domains, a transmembrane domain, and a cytoplasmic region. No canonical 'TATA' box was found upstream of the cap site. About 110 bp upstream of the transcription initiation site, an 18-bp element was found that is homologous to sequences found in the promoter of human myeloperoxidase (606989) and neutrophil elastase (130120) genes.
