Protein names

B-lymphocyte antigen CD19 , B-lymphocyte surface antigen B4 , Differentiation antigen CD19 , T-cell surface antigen Leu-12 , CD antigen CD19

Protein function

Assembles with the antigen receptor of B-lymphocytes in order to decrease the threshold for antigen receptor-dependent stimulation.

Involvement in 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. . Note: The disease is caused by mutations affecting the gene represented in this entry.

Protein sequence and domain

Contains 2 Ig-like C2-type (immunoglobulin-like) domains.

Protein post-translational modifications

Phosphorylated on serine and threonine upon DNA damage, probably by ATM or ATR. Phosphorylated on tyrosine following B-cell activation. Phosphorylated on tyrosine residues by LYN.

Protein cellular localization

Membrane; Single-pass type I membrane protein
