Spectroscopic monitoring is applied to detect structural alterations for homodimeric adhesion/growth-regulatory galectins. Mammalian galectin-1 and the avian ortholog CG-1B, due to their distinct patterns of cysteine positioning, can undergo oxidation. When monitoring tryptophan fluorescence anisotropy comparatively, an indicator of structural changes affecting rotational diffusion, segmental motion...
Characterization of all members of a gene family established by gene divergence is essential to delineate distinct or overlapping expression profiles and functionalities. Their activity as potent modulators of diverse physiological processes directs interest to galectins (endogenous lectins with β‐sandwich fold binding β‐galactosides and peptide motifs), warranting their study with the long‐term aim...
Intrafamily gene diversification has led to three prototype galectins in chicken [i.e., chicken galectin (CG)-1A, CG-1B, and CG-2] that show distinct expression profiles and developmental regulation. In order to pinpoint structural disparities among them, we determined the crystal structure of CG-1B. Alteration of the position of the Trp ring in the lectin site and the presence of only two ordered...
