Function FUNCTION: Functions as a coreceptor for the B-cell antigen receptor complex (BCR) on B-lymphocytes (PubMed:29523808). Decreases the threshold for activation of downstream signaling pathways and for triggering B-cell responses to antigens (PubMed:1373518, PubMed:16672701, PubMed:2463100). Activates signaling pathways that lead to the activation of phosphatidylinositol 3-kinase and the mobilization of intracellular Ca(2+) stores (PubMed:12387743, PubMed:16672701, PubMed:9317126, PubMed:9382888). Is not required for early steps during B cell differentiation in the blood marrow (PubMed:9317126). Required for normal differentiation of B-1 cells (By similarity). Required for normal B cell differentiation and proliferation in response to antigen challenges (PubMed:1373518, PubMed:2463100). Required for normal levels of serum immunoglobulins, and for production of high-affinity antibodies in response to antigen challenge (PubMed:12387743, PubMed:16672701, PubMed:9317126). {ECO:0000250\|UniProtKB:P25918, ECO:0000269\|PubMed:12387743, ECO:0000269\|PubMed:1373518, ECO:0000269\|PubMed:16672701, ECO:0000269\|PubMed:2463100, ECO:0000269\|PubMed:29523808, ECO:0000269\|PubMed:9317126, ECO:0000269\|PubMed:9382888}.

Membrane raft {ECO:0000250\|UniProtKB:P25918}; Single-pass type I membrane protein {ECO:0000250\|UniProtKB:P25918}.
Tissues TISSUE SPECIFICITY: Detected on marginal zone and germinal center B cells in lymph nodes (PubMed:2463100). Detected on blood B cells (at protein level) (PubMed:16672701, PubMed:2463100). {ECO:0000269\|PubMed:16672701, ECO:0000269\|PubMed:2463100}.
Structure SUBUNIT: Interacts with CR2/CD21 (PubMed:1702139). Part of a complex composed of CD19, CR2/CD21, CD81 and IFITM1/CD225 in the membrane of mature B-cells (PubMed:1383329). Interacts directly with CD81 (via the second extracellular domain); this interaction is initiated early during biosynthesis in the ER/pre-Golgi compartments and is essential for trafficking and compartmentalization of CD19 receptor on the cell surface of activated B cells (PubMed:16449649). Interacts with VAV (PubMed:10706702). Interacts with GRB2 and SOS when phosphorylated on Tyr-348 and/or Tyr-378. Interacts with PLCG2 when phosphorylated on Tyr-409 (PubMed:10706702). Interacts with LYN (PubMed:7687428). Interacts (when tyrosine phosphorylated) with the regulatory p85 subunit of phosphatidylinositol 3-kinase (PIK3R1 or PIK3R2) (PubMed:7684160). Interacts with GRB2 (PubMed:29523808). {ECO:0000269\|PubMed:10706702, ECO:0000269\|PubMed:1383329, ECO:0000269\|PubMed:16449649, ECO:0000269\|PubMed:1702139, ECO:0000269\|PubMed:29523808, ECO:0000269\|PubMed:7684160, ECO:0000269\|PubMed:7687428}.
Post-translational modification PTM: Phosphorylated on tyrosine following B-cell activation (PubMed:10706702, PubMed:12387743, PubMed:7684160, PubMed:7687539). Phosphorylated on tyrosine residues by LYN (PubMed:7687428). Tyrosine residues are phosphorylated sequentially after activation of the B cell receptor. Phosphorylation of Tyr-531 is extremely rapid, followed by phosphorylation at Tyr-409. In contrast, phosphorylation of Tyr-500 appears more slowly and is more transient, returning rapidly to basal levels (By similarity). {ECO:0000250\|UniProtKB:P25918, ECO:0000269\|PubMed:10706702, ECO:0000269\|PubMed:12387743, ECO:0000269\|PubMed:7684160, ECO:0000269\|PubMed:7687428, ECO:0000269\|PubMed:7687539}.
Involvement in disease DISEASE: Immunodeficiency, common variable, 3 (CVID3) [MIM:613493]: A primary immunodeficiency characterized by antibody deficiency, hypogammaglobulinemia, recurrent bacterial infections and an inability to mount an antibody response to antigen. The defect results from a failure of B-cell differentiation and impaired secretion of immunoglobulins; the numbers of circulating B-cells is usually in the normal range, but can be low. {ECO:0000269\|PubMed:16672701}. Note=The disease is caused by variants affecting the gene represented in this entry.
