Active Recombinant Human QSOX1 protein, His-tagged

• Cat.No.: QSOX1-285H
• Product Overview: Recombinant Human QSOX1(Ser33-Ala546) fused with an N-terminal Met and 6-His tag was expressed in E. coli.

Specification

• Species: Human
• Source: E.coli
• Tag: His
• Protein Length: 33-546 a.a.
• Description: Sulfhydryl Oxidase-1 (QSOX1) is an approximately 80 kDa enzyme that contains thioredoxin and sulfhydryl oxidase domains. It is synthesized with a C-terminal transmembrane segment, but soluble secreted forms can be generated by alternative splicing or proteolytic shedding within the Golgi. Within the region encompassing both enzymatic domains and the central region, human QSOX1 shares 79% aa sequence identity with mouse and rat QSOX1. It plays a role nascent protein folding by mediating disulfide oxidation. This activity is required for Laminin incorporation into the extracellular matrix. QSOX1 is up-regulated in many cancers and supports tumor cell proliferation and invasion.
• Predicted N Terminal: Met
