  • FunctionPossible adhesion molecule with a role in early hematopoiesis by mediating the attachment of stem cells to the bone marrow extracellular matrix or directly to stromal cells. Could act as a scaffold for the attachment of lineage specific glycans, allowing stem cells to bind to lectins expressed by stromal cells or other marrow components. Presents carbohydrate ligands to selectins.
  • Tissue specificitySelectively expressed on hematopoietic progenitor cells and the small vessel endothelium of a variety of tissues.
  • Sequence similaritiesBelongs to the CD34 family.
  • Developmental stageOn early hematopoietic progenitor cells.
  • Post-translational
    Highly glycosylated.
    Phosphorylated on serine residues by PKC.

  • ab30375 staining CD34 in human intestinal tissue by Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded tissue sections). The sections were fixed in paraformaldehyde prior to blocking with 10% serum for 1 hour at 20°C. The primary antibody was diluted 1/50 in PBS/BSA and incubated with the sample for 12 hours at 4°C.
