T-PA Protein, Human (HEK293, His)
Based on 5 publication(s) in Google Scholar
T-PA is a key proteolytic enzyme that coordinates the conversion of the abundant but inactive zymogen plasminogen to its active form plasmin via hydrolysis of a single Arg-Val bond. This enzymatic conversion helps regulate plasmin-mediated proteolysis, a key process in tissue remodeling, degradation, and various pathophysiological events. T-PA Protein, Human (HEK293, His) is the recombinant human-derived T-PA protein, expressed by HEK293 , with C-6*His labeled tag.

Description
T-PA is a key proteolytic enzyme that coordinates the conversion of the abundant but inactive zymogen plasminogen to its active form plasmin via hydrolysis of a single Arg-Val bond. This enzymatic conversion helps regulate plasmin-mediated proteolysis, a key process in tissue remodeling, degradation, and various pathophysiological events. T-PA Protein, Human (HEK293, His) is the recombinant human-derived T-PA protein, expressed by HEK293 , with C-6*His labeled tag.
Background
Tissue plasminogen activator (t-PA) is a pivotal protein that catalyzes the conversion of the abundant, yet inactive, zymogen plasminogen into the active protease plasmin, achieved by hydrolyzing a single Arg-Val bond in plasminogen. This enzymatic process is integral in controlling plasmin-mediated proteolysis, thereby playing a crucial role in tissue remodeling, degradation, and cell migration, as well as influencing various physiopathological events. Furthermore, t-PA exhibits functional significance during oocyte activation, participating in the cortical granule reaction in the zona reaction, which contributes to the prevention of polyspermy and serves as a protective mechanism during fertilization (By similarity). The multifaceted roles of t-PA underscore its importance in both physiological and reproductive processes, emphasizing its regulatory functions in proteolysis and cellular events.
In Vitro
T-PA Protein, Human (2.5-20 μg/mL, 48 h) enhances the adhesion and migration of T cells to bEnd.3 cells, upregulates the expression of ICAM-1 on the surface and in bEnd.3 cells[1].
In Vivo
T-PA Protein, Human (250 μg/kg, iv, once daily for 7 days) causes the early onset of experimental autoimmune encephalomyelitis (EAE) and increased disease severity in mouse MOG 35-55 (HY-P1240)-induced EAE model[1].
Verified Bioactivity
Measured by its ability to cleave a peptide substrate, N-carbobenzyloxy-Gly-Gly-Arg-7-amido-4-methylcoumarin (Z-GGR-AMC). Read at excitation and emission wavelengths of 380 nm and 460 nm (top read). The specific activity is >500.47 pmol/min/µg, as measured under the described conditions.
