SUBCELLULAR LOCALIZATION

extracellular

basic FUNCTION	stimulating DNA synthesis, mitosis, glycolysis, intracellular cAMP accumulation, prostaglandin E2 secretion, synthesis of hyaluronic acid and sulfated glycosaminoglycan and the formation and secretion of plasminogen activator by human synovial cells
	being a potent chemoattractant and activator for neutrophils
	stimulates the priming of osteoclast progenitors for differentiation into osteoclasts (Nakao 2009)
	has the potential to induce inflammatory responses within the atherosclerotic plaque (Smith 2006)
	may be playing a role to limit platelet-activating factor -dependent vascular tissue damage by preventing degranulation of neutrophils without affecting their migration into the inflamed tissue (Schwartzkopff 2002)

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

coagulation/hemostasis

text	glucose transporter
	blood clotting

PATHWAY

metabolism

a component

INTERACTION

DNA

RNA

small molecule

protein	interacting with IGF2 (has the ability to strongly stimulate osteoclastogenesis by regulating PPBP expression in stromal cells and SDF1 expression in osteoblastic cells) (Nakao 2009)
	with PPBP may promote the formation of giant osteoclasts (Nakao 2009)
