背景介绍
The protein encoded by this gene binds to the cytoplasmic
tail of CD2, an effector of T cell activation and adhesion,
negatively affecting CD2-triggered T cell activation. The encoded
protein appears to be a scaffold protein and a regulator of the
actin cytoskeleton. It has also been shown to bind ABL1, PTPN18,
WAS, CD2AP, and PTPN12. Mutations in this gene are a cause of PAPA
syndrome.
组织表达
Highly expressed in the peripheral blood leukocytes, granulocytes and monocytes, namely in T-cells and natural killer cells, and in spleen. Weakly expressed in the thymus, small intestine, lung and placenta.
细胞定位
Cytoplasm. Cell membrane; Peripheral membrane protein. Cell projection, uropodium. Cytoplasm, cytoskeleton. Cytoplasm, perinuclear region {ECO:0000250|UniProtKB:P97814}. Cell projection, lamellipodium {ECO:0000250|UniProtKB:P97814}. Cleavage furrow {ECO:0000250|UniProtKB:P97814}. Note=Mainly cytoplasmic in T-cells (PubMed:9857189). Colocalizes in cluster with CD2 near the cell surface membrane in activated T-cells (PubMed:9857189). In monocytes, forms a branched filamentous network in the cytoplasm (PubMed:19584923). In transfected cells, forms relatively straight filaments radiating out from the nucleus (PubMed:19584923). Filament formation requires an intact tubulin cytoskeleton (PubMed:19584923). In migrating neutrophils, colocalizes with PIP5K1C and DNM2 to the trailing edge of the uropod in a actin-dependent manner (PubMed:18480402). Colocalized with PTPN12 in the cytoplasm and the perinuclear region. During interphase, colocalizes with F-actin in the cortical cytoskeleton, lamellipodia, and stress fibers. In dividing cells, colocalizes with the F-actin rich cytokinetic cleavage furrow. Colocalized with CD2AP and WAS in the actin cytoskeleton within the cytoplasm. Colocalized with CD2, CD2AP and WAS at the site of T-cell:APC contact (By similarity). {ECO:0000250|UniProtKB:P97814, ECO:0000269|PubMed:18480402, ECO:0000269|PubMed:19584923, ECO:0000269|PubMed:9857189}
