Prediction of proprotein convertase cleavage sites.
Many secretory proteins and peptides are synthesized as inactive precursors that in addition to signal peptide cleavage undergo post-translational processing to become biologically active polypeptides. Precursors are usually cleaved at sites composed of single or paired basic amino acid residues by members of the subtilisin/kexin-like proprotein convertase (PC) family. In mammals, seven members...
متن کاملEndothelial lipase is inactivated upon cleavage by the members of the proprotein convertase family.
Mature endothelial lipase (EL) is a 68 kDa glycoprotein. In HepG2 cells infected with adenovirus encoding human EL, the mature EL was detectable in the cell lysates and heparin-releasable fractions. In contrast, cell media of these cells contained two EL fragments: an N-terminal 40 kDa fragment and a C-terminal 28 kDa fragment. N-terminal protein sequencing of the His-tagged 28 kDa fragment rev...
متن کاملThe secretory proprotein convertase neural apoptosis-regulated convertase 1 (NARC-1): liver regeneration and neuronal differentiation.
Seven secretory mammalian kexin-like subtilases have been identified that cleave a variety of precursor proteins at monobasic and dibasic residues. The recently characterized pyrolysin-like subtilase SKI-1 cleaves proproteins at nonbasic residues. In this work we describe the properties of a proteinase K-like subtilase, neural apoptosis-regulated convertase 1 (NARC-1), representing the ninth me...
متن کاملHow does mutant proprotein convertase neural apoptosis-regulated convertase 1 induce autosomal dominant hypercholesterolemia?
In the secretory pathway of the cell, many biologically inactive precursor proteins are processed by limited proteolysis to produce biologically active peptides and proteins. The enzymes that perform these cleavages are referred to as subtilisin-like proprotein convertases (SPCs).1 Seven members of the SPC family are known. One, the subtilisin kexin isoenzyme-1/site-1-protease (SKI-1/S1P), has ...
متن کاملProprotein convertase cleavage liberates a fibrillogenic fragment of a resident glycoprotein to initiate melanosome biogenesis
Lysosome-related organelles are cell type-specific intracellular compartments with distinct morphologies and functions. The molecular mechanisms governing the formation of their unique structural features are not known. Melanosomes and their precursors are lysosome-related organelles that are characterized morphologically by intralumenal fibrous striations upon which melanins are polymerized. T...
