Target Details

  • Target: CD22
  • Target molecular weight:
  • Target background: SIGLEC2 is first expressed in the cytomplasm of pre- and pro- B cells. SIGLEC2 is broadly expressed in normal and neoplastic B cells and absent from other leucocytes and tissues. SIGLEC2 is a member of the immunoglobulin superfamily and serves as an adhesion receptor for sialic acid-bearing ligands expressed on erythrocytes and all leukocyte classes. It also associates with tyrosine kinases and play a role in signal transduction and B-cell activation. SIGLEC2 is strongly expressed in hairy cell leukaemias.
