Protein Tag: N-Sumo
Uniprot: P02775
Accession: P02775
Background: Pro-platelet basic protein (PPBP) is also known as Chemokine (C-X-C motif) ligand 7 (CXCL7) and nucleosome assembly protein (Nap-2). Nap-2 / PPBP / CXCL7 is released in large amounts from platelets following their activation and is a platelet-derived growth factor that belongs to the CXC chemokine family. This growth factor is a potent chemoattractant and activator of neutrophils. Nap-2 / PPBP / CXCL7 has been shown to stimulate various cellular processes including DNA synthesis , mitosis , glycolysis , intracellular cAMP accumulation , prostaglandin E2 secretion , and synthesis of hyaluronic acid and sulfated glycosaminoglycan. It also stimulates the formation and secretion of plasminogen activator by synovial cells. Nap-2 is a ligand for CXCR1 and CXCR2 , and Nap-2 , Nap-2 (73) , Nap-2 (74) , Nap-2 (1-66) , and most potent Nap-2 (1-63) are chemoattractants and activators for neutrophils.
