Galectins are a family of carbohydrate-binding proteins that play crucial roles in various physiological and pathological processes. They are characterized by their affinity for β-galactoside residues and are involved in inflammation, immune responses, cell migration, autophagy, and signaling . Galectins are synthesized as cytosolic proteins and can interact with both carbohydrate and non-carbohydrate binding partners .
Galectins were initially discovered due to their galactoside-binding activity. They were defined as a protein family based on conserved β-galactoside-binding sites within their characteristic carbohydrate recognition domains (CRDs), which are approximately 130 amino acids long . The galectin family has evolved through tandem and en-mass genome duplications, resulting in over 15 known vertebrate galectins .
Galectin-13, also known as placental protein 13 (PP13), is a member of the galectin family. It is predominantly expressed in the placenta and has been implicated in various reproductive processes. Galectin-13 is involved in the regulation of immune responses at the maternal-fetal interface, promoting immune tolerance and contributing to successful pregnancy outcomes .
Galectin-13 has several important functions:
