Overview
CD170, also known as Siglec 5 (sialic acid binding Ig-like lectin 5) is a type 1 transmembrane glycoprotein containing two cytoplasmic immunoreceptor tyrosine inhibitory motifs (ITIMs) . CD170 forms homodimers and functions as an inhibitory receptor able to downregulate cell activation. It binds to alpha2, 3- and alpha2, 6-linked sialic acid ligands, e.g. on glycophorin A (CD235a) . Aberrant expression of CD170 by CD34+ progenitor cells can be observed in case of acute myeloid leukemias.
Specificity:
The mouse monoclonal antibody 1A5 recognizes an extracellular epitope of CD170 (Siglec-5, sialic acid binding Ig-like lectin 5), a transmembrane glycoprotein expressed strongly by neutrophils, macrophages activated during infections, monocytes, and dendritic cells. As in case with other anti-CD170 antibodies, this antibody crossreacts with Siglec-14, whose first two Ig domains are almost identical to those of CD170.
