Product Specs

Introduction
Sialic Acid Binding Ig Like Lectin 5, also known as SIGLEC5, is a member of the immunoglobulin superfamily and SIGLEC family. It contains 2 Ig-like C2-type domains and 1 Ig-like V-type domain. SIGLEC5 is expressed by monocytic/myeloid lineage cells and at high levels in peripheral blood leukocytes, spleen, and at lower levels in lymph node, appendix, pancreas, lung, and thymus.

Product Science Overview

Gene and Protein Information
  • Gene Name: SIGLEC5
  • Protein Name: Sialic acid-binding Ig-like lectin 5
  • Alternative Names: CD33 antigen-like 2, Obesity-binding protein 2 (OB-BP2), CD170 .
Structure and Function

Siglec-5 is a protein-coding gene that encodes a putative adhesion molecule. This molecule mediates sialic-acid dependent binding to cells, binding equally to alpha-2,3-linked and alpha-2,6-linked sialic acid . The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface .

Biological Role

Siglec-5 plays a crucial role in the immune system. It is a member of the CD33-related subset of Siglecs and inhibits the activation of several cell types, including monocytes, macrophages, and neutrophils . This inhibition is significant for immune regulation and preventing overactivation of immune responses.

Clinical Relevance

Siglec-5 has been implicated in various diseases and immune responses. For instance, the binding of group B Streptococcus (GBS) to Siglec-5 plays a role in GBS immune evasion . Additionally, diseases associated with SIGLEC5 include gonococcal bursitis .

Research and Applications

Recombinant human Siglec-5 is used in research to study its role in cell-cell interactions and immune modulation. When expressed on COS cells or as a recombinant protein fused to the Fc region of human IgG1, Siglec-5 can mediate sialic acid–dependent binding to human erythrocytes and soluble glycoconjugates .
