Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the ‘correct annotation’ for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>
-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Snake venom metalloproteinase lebetase: fibrinolytic and fibrinogenolytic metalloproteinase that hydrolyzes the Aalpha-chain and more slowly the Bbeta-chain of fibrin and fibrinogen. Its fibrinolytic activity is direct, without any plasminogen activation. Also hydrolyzes casein and B-chain of oxidized insulin. Inhibits ADP-induced and collagen-induced platelet aggregation. Shows low hemorrhagic activity. Cleaves the plasma proteinase inhibitors alpha2-macroglobulin (A2M) and pregnancy zone protein (PZP), and is inhibited by them. The metalloprotease has no strict P1-P1' specificity requirement. Hydrolysis at sites with a Pro residue at P1 is observed with bradykinin, substance P, PZP and alpha chain fibrinogen (FGA) (PubMed:11910177).6 Publications
Disintegrin VLE5A: poor inhibitor of platelet aggregation. The disintegrin inhibits the adhesion of the alpha-4/beta-1 (ITGA4/ITGB1) integrin to VCAM-1. Inhibition on alpha-2b/beta-3 (ITGA2B/ITGB3) is low (By similarity).By similarity

Miscellaneous

2 lebetase isoforms have been isolated designated lebetase I (22.719 Da, pI 5.0) and lebetase II (22.912 Da, pI 5.3).1 Publication
Disintegrin VLE5A does not interact with the collagen-binding alpha-1/beta-1 (ITGA1/ITGB1) and alpha-2/beta-1 (ITGA2/ITGB1) integrins.By similarity
The disintegrin belongs to the dimeric disintegrin subfamily.

<p>This subsection of the ‘Function’ section provides information relevant to cofactors. A cofactor is any non-protein substance required for a protein to be catalytically active. Some cofactors are inorganic, such as the metal atoms zinc, iron, and copper in various oxidation states.

Fibrinolytic and caseinolytic activities are inhibited by Cd2+, Cu2+ and Co2+ ions. Not inhibited by Mg2+, Ca2+ and Ba2+. Also inhibited by EDTA, EGTA and 1,10-phenanthroline.2 Publications
