SUBCELLULAR LOCALIZATION	extracellular
text	key component of the hyaluronan-rich cumulus extracellular matrix, which forms around the oocyte prior to ovulation

basic FUNCTION	playing a role in the inflammatory response (antifungal innate immune response)
	playing key roles in the regulation of innate resistance to pathogens, inflammatory reactions, possibly clearance of self- components and female fertility
	may play a role in the innate immune response and inflammatory reactions in the kidney
	fluid-phase pattern recognition receptor that plays a nonredundant role in innate immunity and female fertility
	involved in C1q recognition and complement activation
	multifunctional soluble pattern recognition receptor acting as a non-redundant component of the humoral arm of innate immunity involved in fine-tuning inflammation, matrix deposition, angiogenesis and, in particular, in female fertility
	translocates at the surface of late apoptotic neutrophils and acts as an 'eat-me' molecule for their recognition and capture by macrophages
	coordinated expression of PTX3 and TNFAIP6 may play a role in ECM remodeling at sites of inflammation
	important role in innate immune responses and in female fertility
	participates in the attenuation of macrophage-mediated phagocytosis of damaged neuron cells
	role for astrocytic CEBPD and the CEBPD-regulated molecule PTX3 in the accumulation of damaged neurons, which is a hallmark of Alzheimer disease pathogenesis

CELLULAR PROCESS

PHYSIOLOGICAL PROCESS

inflammation

text	inflammatory response

PATHWAY

metabolism

signaling

a component	homomultimer, disulfide-linked
	being mainly composed of covalently linked octamers
	composed of multiple protomers, each composed of distinct N- and C-terminal domains (eight identical protomers, associated through disulfide bonds, forming an elongated and asymmetric, molecule with two differently sized domains interconnected by a stalk)

INTERACTION

DNA

RNA

small molecule

protein	interacting with TNFAIP6 (coordinated expression of PTX3 and TNFAIP6 may play a role in ECM remodeling at sites of inflammation)
	CEBPD target in astrocytes
	binds to the classical and lectin pathway regulator C4b-binding protein (C4BPA)
