CD177

CD177 (CD177 Molecule) is a Protein Coding gene. Diseases associated with CD177 include Polycythemia and Polycythemia Vera. Among its related pathways are Response to elevated platelet cytosolic Ca2+ and Innate Immune System. An important paralog of this gene is TEX101.

CD177 Molecule

In association with beta-2 integrin heterodimer ITGAM/CD11b and ITGB2/CD18, mediates activation of TNF-alpha primed neutrophils including degranulation and superoxide production (PubMed:21193407).
In addition, by preventing beta-2 integrin internalization and attenuating chemokine signaling favors adhesion over migration (PubMed:28807980).
Heterophilic interaction with PECAM1 on endothelial cells plays a role in neutrophil transendothelial migration in vitro (PubMed:17580308).
However, appears to be dispensable for neutrophil recruitment caused by bacterial infection in vivo (PubMed:23461681).
Acts as a receptor for the mature form of protease PRTN3 allowing its display at the cell surface of neutrophils (PubMed:17244676, PubMed:18462208).
By displaying PRTN3 at the neutrophil cell surface, may play a role in enhancing endothelial cell junctional integrity and thus vascular integrity during neutrophil diapedesis (PubMed:23202369).

Cell membrane; Secreted; Membrane raft; Cytoplasmic granule membrane; Lamellipodium. Cell surface expression on neutrophils is increased upon TNF-alpha, fMLP or CXCL8/IL8-mediated stimulation (PubMed:17244676, PubMed:17580308). In neutrophils, stored predominantly in secondary and tertiary granules (PubMed:18462208). Can also be shedded from the cell membrane (PubMed:12239154, PubMed:18462208). Localizes to lamellar protrusions in spreading neutrophils (PubMed:28807980).

N-glycosylated.
A soluble form may also be produced by proteolytic cleavage at the cell surface (shedding).
