The ITAM-bearing transmembrane adaptor DAP12 in lymphoid and myeloid cell function
Abstract
DAP12, an ITAM-bearing transmembrane adaptor protein, associates non-covalently with receptors in natural killer (NK) and myeloid cells, and provides signaling function via the Syk and ZAP-70 tyrosine kinase activation pathways. Humans and mice lacking DAP12 (DAP12(-/-)) show normal development of hematopoietic cells. However, DAP12(-/-) humans develop presenile dementia and bone cysts, and DAP12(-/-) mice show impaired immune responses.
