Target Details

Target: CD19 (CD19 Molecule (CD19))

Alternative Name: CD19

Background: CD19 is a 95 kDa transmembrane glycoprotein that plays a central role in B cell activation and humoral immune responses. Functions as coreceptor for the B-cell antigen receptor complex (BCR) on B-lymphocytes. Decreases the threshold for activation of downstream signaling pathways and for triggering B-cell responses to antigens. Activates signaling pathways that lead to the activation of phosphatidylinositol 3-kinase and the mobilization of intracellular Ca2 stores.

Molecular Weight: 30.7 kDa. Due to glycosylation, the protein migrates to 55-68 kDa based on Bis-Tris PAGE result.

UniProt: P25918

Pathways: Fc-epsilon Receptor Signaling Pathway, EGFR Signaling Pathway, Neurotrophin Signaling Pathway
