Cd19 - CD19 molecule

Predicted to be involved in several processes, including B cell activation; B cell receptor signaling pathway; and positive regulation of phosphatidylinositol 3-kinase activity. Predicted to act upstream of or within positive regulation of release of sequestered calcium ion into cytosol. Predicted to be integral component of plasma membrane. Predicted to be part of protein-containing complex. Predicted to be active in external side of plasma membrane. Human ortholog(s) of this gene implicated in common variable immunodeficiency. Orthologous to human CD19 (CD19 molecule). [provided by Alliance of Genome Resources, Apr 2022]
