LAB linker for activation of B cells (LAB) is an adaptor protein. B cell antigen receptor signaling leads to its phosphorylation and interaction with the adaptor protein Grb2. Decreased expression leads to a reduction in BCR-mediated calcium flux and Erk activation. Localized to lipid rafts. Note: This description may include information from UniProtKB.
