Protein Function and Prediction

Pcolce2 encodes PCPE2, a ubiquitously expressed type II procollagen C-proteinase enhancer that functions with BMP-1 to produce pNα1(II) chains (1-4). Another study shows that PCPE2 modulates HDL levels (4) and proteolytically processes pro-apolipoprotein (apo) A-I by enhancing the cleavage of the hexapeptide extension present at the N-terminus of apoA-I (3).


PCOLCE2 is highly expressed in the adult human aorta and portions of the adult heart (2)PCOLCE2 is also highly expressed in the pituitary gland, bladder, mammary gland, and trachea (2).


Lipid profiles of Pcolce2 knockout mice showed a marked increase in plasma apoA-I and HDL-cholesterol (HDL-C) levels in PCPE2 KO mice compared with wild-type littermates, regardless of gender or diet (3). In addition, ABCA1-dependent cholesterol efflux is defective (3).
