Description

The recombinant Human TXN protein synthesis in e.coli cells necessitates the incorporation of a DNA fragment encoding the Human TXN protein (2-105aa) into a plasmid vector, followed by the transformation of this vector into e.coli cells. After screening for positive cells, they are cultured and induced to express the TXN protein. The protein carries a N-terminal GST tag. Cell lysis is performed to gather the recombinant Human TXN protein, which undergoes affinity purification and is then analyzed using SDS-PAGE and subsequent staining of the gel with Coomassie Brilliant Blue. The purity of the resulting recombinant Human TXN protein reaches up to 90%.

Target Background

Function

Participates in various redox reactions through the reversible oxidation of its active center dithiol to a disulfide and catalyzes dithiol-disulfide exchange reactions. Plays a role in the reversible S-nitrosylation of cysteine residues in target proteins, and thereby contributes to the response to intracellular nitric oxide. Nitrosylates the active site Cys of CASP3 in response to nitric oxide (NO), and thereby inhibits caspase-3 activity. Induces the FOS/JUN AP-1 DNA-binding activity in ionizing radiation (IR) cells through its oxidation/reduction status and stimulates AP-1 transcriptional activity.; ADF augments the expression of the interleukin-2 receptor TAC (IL2R/P55).
