Galectins are animal lectins that recognize carbohydrates and play important roles in cellular homeostasis. Recent studies have shown that galectins accumulate around damaged endocytic vesicles and control cellular responses by interacting with cellular proteins, such as autophagy. The differential regulatory effects among galectins are also highlighted in this review.
Galectins are animal lectins that recognize carbohydrates and play important roles in maintaining cellular homeostasis. Recent studies have indicated that under a variety of challenges, intracellular galectins bind to host glycans displayed on damaged endocytic vesicles and accumulate around these damaged organelles. Accumulated galectins then engage cellular proteins and subsequently control cellular responses, such as autophagy. In this review, we have summarized the stimuli that lead to the accumulation of galectins, the molecular mechanisms of galectin accumulation, and galectin-mediated cellular responses, and elaborate on the differential regulatory effects among galectins.
