SUBCELLULAR LOCALIZATION	extracellular
	plasma membrane
text	overexpressed in normal memory B cells

basic FUNCTION	putatively involved in sperm maturation
	may be playing a role in the interaction of lymphocytes with ITGA4B1-expressing leukocytes
	playing a role in cell proliferation and progression of the lung carcinomas
	may function as positive regulator of growth and differentiation of dental papilla mesenchymal cells and act as an important molecule mediating reciprocal epithelial-mesenchymal signaling during tooth organ development
	involved in cell proliferation through enhanced bioavailability of IGFI released from the IGF1/IGFBP3 complex by selective IGFBP3 cleavage in breast carcinomas
	degrading proteoglycans and may be involved in cartilage degradation in osteoarthritis
	may promote angiogenesis in the breast carcinoma tissues by releasing vascular endothelial growth factor165 (VEGF165) after digestion of CTGF in the CTGF/VEGF165 complex

CELLULAR PROCESS	cell life, differentiation
	protein, degradation

PHYSIOLOGICAL PROCESS

PATHWAY

metabolism

signaling

a component

INTERACTION

DNA

RNA

small molecule	metal binding,
	Zn2+

protein	ligand for ITGA4B1
	interact with integrins and is involved in the digestion of IGFBP3 through release of IGF1, a potent inducer of cell proliferation
	interacting with SELPLG (ADAM28 promotes SELPLG/P-selectin-mediated leukocyte rolling adhesion to endothelial cells and subsequent infiltration into tissue spaces through interaction with SELPLG on leukocytes under inflammatory conditions)
	also involved in activation of EGFR, MAPK1, MAPK3 and release of CD44
	CTGF is a novel substrate of ADAM28
