3.4.24.19	Frizzled-related protein	secreted Frizzled-related protein sFRP2 serves as a direct enhancer of procollagen C proteinase activity of tolloid-like metalloproteinases. The level of fibrosis, in which procollagen processing by tolloid-like proteinases has a rate-limiting role, is markedly reduced in Sfrp2-null mice subjected to myocardial infarction. This reduced level of fibrosis is accompanied by significantly improved cardiac function	700348

3.4.24.19	additional information	both PCPE1 and PCPE2 are located in the extracellular matrix, where they facilitate bone morphogenetic protein 1 (BMP1) cleavage of C-terminal procollagen propeptides. PCPE2 and PCPE1 have different tissue distributions and heparin-binding affinities, suggesting a functional divergence. PCPE2 is heavily expressed in heart tissue in contrast to PCPE1. Both PCPE1 and PCPE2 have two CUB (Complement C1r/C1s, Uegf, Bmp1) domains separated by a short linker region, with each domain consisting of about 110 residues containing a beta-sandwich fold that mediates a variety of protein-protein interactions. Phenotype of PCPE2-/- mice, overview	754110	
3.4.24.19	PCPE-1	enhances degredation of procollagen type I 5 fold, enhances C-terminal processing of procollagen type III when this substrate is in its native, disulfide-bonded conformation, has no effect on the in vitro BMP-1 processing of procollagen VII, procollagen V N-propeptide, laminin 5 gamma2 chain, osteoglycin, prolysyl oxidase or chordin	669352	
3.4.24.19	procollagen C-endopeptidase enhancer protein 1	PCPE1, a glycoprotein located in the extracellular matrix, enhances the cleavage of C-terminal procollagen by bone morphogenetic protein 1 (BMP1)	754110	
3.4.24.19	procollagen C-endopeptidase enhancer protein 2	PCPE2, a 52-kDa glycoprotein located in the extracellular matrix, enhances the cleavage of C-terminal procollagen by bone morphogenetic protein 1 (BMP1). PCPE2 is not essential for in vivo pro-apoA-I processing. PCPE2 confers atheroprotection to apoA-I by enhancing BMP1-mediated catalytic cleavage, converting pro-apoA-I to mature apoA-I, and stimulating ABCA1-mediated cholesterol flux, but pro-apoA-I processing is not altered in the case of PCPE2 deficiency	754110
