Human Siglec-7/CD328 ELISA Kit PicoKine®

Sialic acid-binding Ig-like lectin 7, also known as CD328 (cluster of differentiation 328) or AIRM1, is a protein that in humans is encoded by the SIGLEC7 gene. And this gene is mapped to chromosome 19. AIRM1 is a novel member of the sialoadhesin family characterized by 3 immunoglobulin-like extracellular domains (1 N-terminal V type and 2 C2 type) and a classic immunoreceptor tyrosine-based inhibitory motif (ITIM) in the cytoplasmic portion. The highest amino acid sequence similarity found was with the myeloid-specific CD33 molecule, and similar to other sialoadhesin molecules, AIRM1 appears to mediate sialic acid-dependent ligand recognition.

Predominantly expressed by resting and activated natural killer cells and at lower levels by granulocytes and monocytes. High expression found in placenta, liver, lung, spleen, and peripheral blood leukocytes.

Putative adhesion molecule that mediates sialic-acid dependent binding to cells. Preferentially binds to alpha-2,3- and alpha-2,6-linked sialic acid. Also binds disialogangliosides (disialogalactosyl globoside, disialyl lactotetraosylceramide and disialyl GalNAc lactotetraoslylceramide) . The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface. In the immune response, may act as an inhibitory receptor upon ligand induced tyrosine phosphorylation by recruiting cytoplasmic phosphatase (s) via their SH2 domain (s) that block signal transduction through dephosphorylation of signaling molecules. Mediates inhibition of natural killer cells cytotoxicity. May play a role in hemopoiesis. Inhibits differentiation of CD34+ cell precursors towards myelomonocytic cell lineage and proliferation of leukemic myeloid cells (in vitro) . .
