Galectins are proteins with beta-galactoside binding. This review details galectin-1 receptors and their roles in various cell functions and biological processes.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Cell Biology

Background:

  • Galectins are animal lectins characterized by specific carbohydrate-recognizing domains and beta-galactoside affinity.
  • They are implicated in diverse biological processes including development, differentiation, tumor metastasis, apoptosis, RNA splicing, and immune regulation.

Purpose of the Study:

  • This review focuses on galectin-1 receptors.
  • It explores the mechanisms through which galectin-1 influences various cell types.

Main Methods:

  • Literature review of galectin-1 interactions.
  • Identification and discussion of known galectin-1 receptors.

Main Results:

  • Galectin-1 interacts with a broad spectrum of cell surface and intracellular molecules.
