NCBI Summary
The galectins are a family of beta-galactoside-binding proteins implicated in modulating cell-cell and cell-matrix interactions. Differential and in situ hybridization studies indicate that this lectin is specifically expressed in keratinocytes and found mainly in stratified squamous epithelium. A duplicate copy of this gene (GeneID:3963) is found adjacent to, but on the opposite strand on chromosome 19. [provided by RefSeq, Jul 2008].

Structural models
Model Confidence:
  •    Very high (pLDDT > 90)
  •    Confident (90 > pLDDT > 70)
  •    Low (70 > pLDDT > 50)
  •    Very low (pLDDT < 50)

  AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.
