General Information
MBP is a peripheral membrane protein, and its interaction with lipids is generally believed to be critical for the formation and stability of the multilamellar myelin sheath. It has been identified as a Ca2+-calmodulin regulated agent for actin polymerization, tropomyosin and actomyosin function, tubulin stabilization, and clathrin assembley. MBP is generally considered to be the antigen responsible for autoimmunity in multiple sclerosis (MS) and it has the capability to induce experimental allergic encephalomyelitis (EAE). MBP is also an endogenous inhibitor of the high-affinity cannabinoid binding site in the brain and a substrate for numerous protein kinases (MAPK, serine/threonine kinase, protein kinase C). MBP is also suggested to be involved in intracellular signalling and as cytoskeletal components.

General Information
BACKGROUND/TECHNICAL INFORMATION MMP-3 hydrolyzes components of the extracellular matrix like proteoglycan, laminin, fibronectin, gelatin and collagen types III, IV and IX. It also activates pro-MMP-9 and pro-MMP-8 and superactivates plasmin activated MMP-1. MMP-3 is secreted as a latent proenzyme and is activated by a variety of proteinases, e.g. plasmin, trypsin, chymotrypsin, cathepsin G or human neutrophil elastase. The activating process generates an active 45kDa species which converts easily to a highly active 28kDa form. Product ALX-201-042 displays the same activity as the 28kDa form.

BACKGROUND/TECHNICAL INFORMATION

Activation of MMP-2 proenzyme and measurement of catalytic activity

1 Preparation and stability of solutions:
∙ APMA-solution: 40mM p-aminophenyl mercuric acetate (APMA) in DMSO. Store at -20°C.
∙ Peptide hydrolysis buffer: 50mM TRIS-HCl, pH 7.5, 150mM NaCl, 5mM CaCl2, 0.025% Brij 35. Solution
  is stable for several weeks at 4°C.
∙ Stock solution of peptide substrate: 100µM solution of Mca-Pro-Leu-Gly-Leu-Dpa-Ala-Arg-NH2 in 20%
  DMSO. Store at -20°C.
∙ Stock solution of unquenched peptide: 10µM solution of Mca-Pro-Leu-NH2 in 20% DMSO. Store at -20°C.

2 Activation:
An aliquot of 19.5μl MMP-2 proenzyme is mixed with 0.5µl APMA solution and is incubated for 60 min. at 37°C.

3 Assay protocol:
The activity of MMP-2 is measured fluorimetrically with a synthetic internally quenched fluorescent substrate according to Knight et al. [1].
An excitation wavelength of 328nm and an emission wavelength of 393nm are set in an appropriate fluorimeter. The instrument is calibrated with the unquenched peptide Mca-Pro-Leu at a concentration corresponding to between 2 and 10% hydrolysis of the protease substrate. Kinetic reactions are conveniently carried out in a constant volume of 2.5ml. The substrate Mca-Pro-Leu-Gly-Leu-Dpa-Ala-Arg is diluted in peptide hydrolysis buffer to a concentration of  0.8µM and equilibrated at a temperature of 37°C. Aliquots of 1 to 2µl of the activation mixture are than added and the increase in fluorescence is recorded over a time interval between 2 and 12 minutes. Activity units per ml enzyme solution are calculated according to the following equation:

Activity (U/ml) = (CMca-Pro-Leu/FMca-Pro-Leu) x (ΔFMca-Pro-Leu-Gly-Leu-Dpa-Ala-Arg/Venzyme) x Vtotal

CMca-Pro-Leu: Concentration of Mca-Pro-Leu used for calibration of the fluorimeter (µmoles/ml).
FMca-Pro-Leu: Fluorescence of Mca-Pro-Leu at the concentration CMca-Pro-Leu used for fluorimeter calibration.
ΔFMca-Pro-Leu-Gly-Leu-Dpa-Ala-Arg: Change in fluorescence during peptide hydrolysis per min.
Vtotal: Volume of peptide hydrolysis reaction (2.5ml).
Venzyme: Volume of added enzyme (0.001 to 0.002ml).

Due to autoproteolytic activity minor bands of activated enzyme may be visible in the preparation.
