Description
General description
Growth-regulated alpha protein (UniProt: P09341; also known as C-X-C motif chemokine 1, CXCL1, GRO-alpha(1-73), Melanoma growth stimulatory activity, MGSA, Neutrophil-activating protein 3, NAP-3) is encoded by the CXCL1 (also known as GRO, GRO1, GROA, MGSA, SCYB1) gene (Gene ID: 2919) in human. CXCL1 is a multi-functional chemokine that displays chemotactic activity for neutrophils. It is synthesized with a signal peptide (aa 1-34), which is subsequently cleaved off to produce the mature protein that can be further cleaved into three chains (aa 4-73; 5-73; and 6-73) via proteolytic cleavage after secretion from peripheral blood monocytes. CXCL1 may play a role in inflammation and exert its effects on endothelial cells in an autocrine fashion. Its levels are reported to be low under basal conditions but increase significantly following active infection. It plays a role in recruiting and activating neutrophils for microbial killing at the tissue site and can also activate the release of proteases and reactive oxygen species. CXCL1 signals through binding to CXCR2, a G-protein coupled receptor. Aberrant expression of CXCL1 has been reported in several cancers and has been associated with oncogenesis, metastasis, angiogenesis and chemoresistance. Clone HL2401 is shown to specifically binds to CXCL1, although it may show slight binding to CXCL2. It is shown to reduce both cellular proliferation and invasion of cancer cells overexpressing CXCL1. It also induces apoptosis and impairs tumor vasculature. (Ref.: Miyake, M., et al. (2019).
