GAL contains a carbohydrate recognition domain (CRD). GAL are known to inhibit chronic inflammation. The CRD is a beta-sandwich long enough to bind a tetrasaccharide. GAL-1 is thought to play a role as autocrine negative growth factor that regulates cell proliferation. GAL-2 is expressed primarily in gastrointestinal tract. GAL-3 has broad biological functionality. GAL-4 has 2 CRDs. GAL-7 is associated with epithelial cells. GAL-8 has a role in cellular defence against bacterial infection and vacuolar damage. GAL-9 affects eosinophil survival. GAL-10 or Charcot-Leyden crystal protein acts on biological membranes to regulate the multifunctional lysophospholipids.
