General description
Sialic acid binding Ig like lectin 15 (SIGLEC15) is part of the Siglec family of glycan-recognition proteins. It is expressed in a subset of macrophages. This type-I transmembrane protein possesses two immunoglobulin-like domains, a transmembrane domain and a short cytoplasmic tail. The SIGLEC15 gene is localized on human chromosome 18q12.3.
Immunogen
Antibody was raised against a 15 amino acid peptide near the amino terminus of human SIGLEC15.
Biochem/physiol Actions
Sialic acid binding Ig like lectin 15 (SIGLEC15) recognizes a tumor-linked glycan structure called the sialyl-Tn (sTn) antigen. It is expressed on tumor-associated macrophages in tumor tissues. The protein acts as a signal transducer. SIGLEC15 associates with the adaptor protein DNAX activation protein of 12kDa (DAP12) and transduces a signal to spleen tyrosine kinase (Syk).

Siglec-15: an immune system Siglec conserved throughout vertebrate evolution.
Glycobiology (2007)
The interaction between Siglec-15 and tumor-associated sialyl-Tn antigen enhances TGF-? secretion from monocytes/macrophages through the DAP12-Syk pathway.

Rationale: Siglec15 is an emerging target for normalization cancer immunotherapy. However, pan-cancer anti-Siglec15 treatment is not yet validated and the potential role of Siglec15 in bladder cancer (BLCA) remains elusive. Methods: We comprehensively evaluated the expression pattern and immunological role

Sialic acid-binding immunoglobulin-like lectin 15 (Siglec-15) has been identified as a crucial immune suppressor in human cancers, comparable to programmed cell death 1 ligand (PD-L1). However, the regulatory mechanisms underlying its transcriptional upregulation in human cancers remain largely unknown. Here
