General description

Siglec-H (UniProt: Q3Y597; also known as Sialic acid binding Ig-like lectin H) is encoded by the Siglech gene (Gene ID: 233274) in murine species. Siglecs are sialic acid-binding immunoglobulin-like lectins that are expressed mostly in the immune system and may be involved in both adhesive and signaling functions. Siglec-H is a type I, CD33-related siglec-like transmembrane glycoprotein that is synthesized with a signal peptide (aa 1-18), which is subsequently cleaved off in the mature form. The mature form has to ig-like domains (aa 32-141 and 151-234) in its extracellular region. Unlike other CD33-related siglecs, it lacks tyrosine-based signaling motifs in its cytoplasmic tail. Siglec-H is shown to be expressed on plasmaocytoid dendritic cells (pDCs) and can serve as a reliable marker for these cells. Siglec-H is also reported to serve as an endocytic receptor expressed on murine pDCs. Action of Siglec-H depends on a 12 kDa DNAX-activating protein (DAP). (Ref.: Zhang, J., et al. (2006).
