NCBI Summary
This gene encodes a member of the sialic acid-binding immunoglobulin-like lectin family. These cell surface lectins are characterized by structural motifs in the immunoglobulin (Ig)-like domains and sialic acid recognition sites in the first Ig V set domain. This family member mediates anti-inflammatory and immunosuppressive signaling. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Oct 2011].

  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.
