human galectin-3, codon optimized for E. coli

Galectin-3 is a 26 kDa protein that binds certain LPS patterns. It especially bind the O-section of the LPS.

Galectins are proteins of the lectin family, which posess carbonhydrate recognition domains binding specifically to β-galactoside sugar residues. In humans, 10 different galectines have been identified, among which is galectin-3.

Galectin-3 has a size of about 31 kDA and is encoded by a single gene, LGALS3. It has many physiological functions, such as cell adhesion, cell growth and differentiation, and contributes to the development of cancer, inflammation, fibrosis and others.

Human galectin-3 is a protein of the lectin-family that was shown to bind the LPS of multiple human pathogens. Some of them, including Pseudomonas aeruginosa protect themselves against the human immune system by mimicking the lipopolysaccharides (LPS) present on human erythrocytes.

Usage and Biology

Pellets of different fusion protein expressions
Expression in the pET17 vector was much more leaky than the expression in the pSBX vectors.
