Introduction
Selenoprotein W 1, also known as SEPW1 is a selenoprotein, which has a
selenocysteine (Sec) residue at its active site. The selenocysteine is encoded
through the UGA codon which normally signals translation termination. The 3'
UTR of selenoprotein genes share a common stem-loop structure, the sec
insertion sequence (SECIS), which is essential for the recognition of UGA as a
Sec codon instead of as a stop signal. SEPW1 shows highest expression in
skeletal muscle and heart, and also involved in oxidation-reduction reactions.
Description
SEPW1 Human Recombinant produced in E.Coli is a single,
non-glycosylated polypeptide chain containing 110 amino acids (1-87 a.a) and
having a molecular mass of 11.8kDa.?
SEPW1 is fused to a 23 amino acid His-tag at N-terminus
& purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
