UniProt Protein Function: | 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. |
UniProt Protein Details: | Protein type:Adaptor/scaffold; Membrane protein, integral Chromosomal Location of Human Ortholog: 7q11.23 Cellular Component: mast cell granule; integral to membrane; plasma membrane; lipid raft Molecular Function:protein binding; SH2 domain binding Biological Process: B cell receptor signaling pathway; B cell activation; calcium-mediated signaling; innate immune response; mast cell degranulation |
NCBI Summary: | This gene is one of the contiguous genes at 7q11.23 commonly deleted in Williams syndrome, a multisystem developmental disorder. This gene consists of at least 14 exons, and its alternative splicing generates 3 transcript variants, all encoding the same protein. [provided by RefSeq, Jul 2008] |
