Anti-LST1 Monoclonal Antibody (Clone:LST1/02)

LST1 (leukocyte-specific transcript, also known as B144) is expressed in cells of myeloid/erythroid lineage (monocytes, granulocytes, dendritic cells, platelets, erythrocytes) . At least 14 alternatively spliced variants (LST1/A - LST1/N) can be detected; some of them (LST1/A, B, C, G, I, K) are transmembrane cell surface-exposed forms, the other are soluble. LST1 induces production of long, thin filopodia in dendritic cells, has an inhibitory effect on lymphocyte proliferation and may have an immunomodulatory role. LST1/A is an 11 kDa transmembrane adaptor present in membrane rafts and forms spontaneously covalent homodimers. Its intracellular domain contains two tyrosine motifs, one of them being an ITIM very similar to such motifs in Siglec.
