Gene: CD19 (CD19 molecule) Homo sapiens
Symbol: CD19
Name: CD19 molecule
Description: Involved in several processes, including B cell proliferation involved in immune response; positive regulation of phosphatidylinositol 3-kinase activity; and positive regulation of release of sequestered calcium ion into cytosol. Localizes to the external side of plasma membrane; integral component of plasma membrane; and protein-containing complex. Implicated in common variable immunodeficiency.
Type: protein-coding
RefSeq Status: REVIEWED
Also known as: B-lymphocyte antigen CD19; B-lymphocyte surface antigen B4; B4; cd19 antigen; CVID3; differentiation antigen CD19; MGC12802; T-cell surface antigen Leu-12
