Functional Studies - Recombinant human TIMP1 protein (Active) (AB280945)
Functional analysis of ab280945.
Fully active determined by its ability to inhibit human MMP2 cleavage of a chromogenic peptide substrate (Mca-PLG-Dpa-AR-NH2).
ED50 is ≤9.7 ng/ml, corresponding to a specific activity of 1.03 x 105 units/mg.
Cell based assay testing is performed on the first lot of protein only and is provided as a reference for protein activity; subsequent lots of protein must pass all biophysical quality control parameters that meet the same parameters as the first lot.

Biological function summary
TIMP1 plays several essential roles beyond inhibiting metalloproteinases. It supports cell proliferation and influences apoptosis. It is part of a larger TIMP family and does not function as part of a complex per se but interacts closely with matrix metalloproteinases (MMPs). By regulating MMP activity TIMP1 balances processes like tissue growth and inflammatory responses which are important for normal development and repair.
Pathways
TIMP1 participates in the regulation of the matrix metalloproteinase pathway impacting tissue homeostasis and repair. It closely associates with proteins such as MMP-9 and MMP-2 within this pathway. TIMP1 also plays a role in cytokine signaling pathways which influence immune responses by interacting with other signaling molecules and receptors that govern these pathways.

General info
Function
Metalloproteinase inhibitor that functions by forming one to one complexes with target metalloproteinases, such as collagenases, and irreversibly inactivates them by binding to their catalytic zinc cofactor. Acts on MMP1, MMP2, MMP3, MMP7, MMP8, MMP9, MMP10, MMP11, MMP12, MMP13 and MMP16. Does not act on MMP14. Also functions as a growth factor that regulates cell differentiation, migration and cell death and activates cellular signaling cascades via CD63 and ITGB1. Plays a role in integrin signaling. Mediates erythropoiesis in vitro; but, unlike IL3, it is species-specific, stimulating the growth and differentiation of only human and murine erythroid progenitors.
Sequence similarities
Belongs to the protease inhibitor I35 (TIMP) family.
Post-translational modifications
The activity of TIMP1 is dependent on the presence of disulfide bonds.. N-glycosylated.
