We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Disease

[TPA_HUMAN] Note=Increased activity of TPA results in increased fibrinolysis of fibrin blood clots that is associated with excessive bleeding. Defective release of TPA results in hypofibrinolysis that can lead to thrombosis or embolism.

Function

[TPA_HUMAN] Converts the abundant, but inactive, zymogen plasminogen to plasmin by hydrolyzing a single Arg-Val bond in plasminogen. By controlling plasmin-mediated proteolysis, it plays an important role in tissue remodeling and degradation, in cell migration and many other physiopathological events. Plays a direct role in facilitating neuronal migration.

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.

Publication Abstract from PubMed

The amino acid sequence of the first domain of tissue-type plasminogen activator (t-PA) includes eight residues that are highly conserved in the type 1 finger domains found in human fibronectin. A construct comprising 50 residues from this finger domain of t-PA has been expressed and its solution structure has been determined by two-dimensional nuclear magnetic resonance spectroscopy. A total of 782 experimental restraints consisting of 723 interproton distances derived from nuclear Overhauser effect measurements, 43 torsion angles, and 16 hydrogen bond restraints were used as the input for dynamical simulated annealing structure calculations. Twenty-eight structures were obtained that satisfied the experimental data with no single distance violation greater than 0.3 A. The average atomic root-mean-square distribution for the backbone atoms of the final structures was 0.41 (+/- 0.13) A for the well defined part of the structure (residues 4 to 47). The overall fold of the t-PA finger domain shows a striking similarity to that of the seventh type 1 repeat of human fibronectin with the side-chains of conserved residues lying in similar conformations. One significant difference between the two molecules is that hydrophobic residues cover the exposed surface of the principal beta-sheet region in the t-PA finger domain. It is suggested that one face of this region may interact with parts of the complete t-PA protein.
