Anti-Ly-49A antibodies, mouse

Clone: REA1018 | Dilution: 1:50
Clone REA1018 recognizes th mouse Ly-49A antigen, an inhibitory cell surface receptor belonging to the Ly-49 receptor family. Ly-49A is a 44 kDa type II transmembrane, disulfide-linked homodimer with C-type lectin extracellular domains. Expression of Ly-49A is found on subset of NK and NK-T cells. Ly-49 family members are both activating and inhibitory receptors and are mainly receptors for MHC class I molecules. Ly-49A interacts strongly with MHC class Ia molecules such as H-2Dd, H-2Dk, and weakly with H-2Db. An inhibitory signal is delivered by Ly-49A engagement via the phosphorylation of immunoreceptor tyrosine based inhibition motif (ITIM) and recruitment of phosphatases SHP-1 and SHP-2. Recognition of cognate ligand bearing cells leads to inhibition of cytotoxic killing of cells by NK cells.
Additional information: Clone REA1018 displays negligible binding to Fc receptors.
