Synapse too exclusive for CD148
kinetochore protein plays both sides of the checkpoint field, according to Weaver et al. on page 551. They show that CENP-E, a mitotic checkpoint-silencing protein, also stimulates the amount of checkpoint inhibitor released from an unattached kinetochore. The mitotic checkpoint is the major mechanism preventing chromosomal loss during mammalian mitosis. Unattached kinetochores generate an inhi...
متن کاملThe tyrosine phosphatase CD148 is excluded from the immunologic synapse and down-regulates prolonged T cell signaling
CD148 is a receptor-like protein tyrosine phosphatase up-regulated on T cells after T cell receptor (TCR) stimulation. To examine the physiologic role of CD148 in TCR signaling, we used an inducible CD148-expressing Jurkat T cell clone. Expression of CD148 inhibits NFAT (nuclear factor of activated T cells) activation induced by soluble anti-TCR antibody, but not by antigen-presenting cells (AP...
متن کاملThrombospondin-1 acts as a ligand for CD148 tyrosine phosphatase.
CD148 is a receptor-type protein tyrosine phosphatase that is expressed in several cell types, including vascular endothelial cells and duct epithelial cells. Growing evidence demonstrates a prominent role for CD148 in negative regulation of growth factor signals, suppressing cell proliferation and transformation. However, its extracellular ligand(s) remain unknown. To identify the ligand(s) of...
متن کاملCase report: BRCA in the Ashkenazi population: are current testing guidelines too exclusive?
The BRCA1/2 genes account for a significant portion of hereditary breast and ovarian cancers and they are especially prevalent in the Ashkenazi Jewish population. Women who have a mutation can prevent breast and ovarian cancer with surgical intervention. We describe an Ashkenazi Jewish patient who illustrates that current testing criteria are too restrictive, particularly for this population of...
متن کاملCD148 Tyrosine Phosphatase Promotes Cadherin Cell Adhesion
CD148 is a transmembrane tyrosine phosphatase that is expressed at cell junctions. Recent studies have shown that CD148 associates with the cadherin/catenin complex and p120 catenin (p120) may serve as a substrate. However, the role of CD148 in cadherin cell-cell adhesion remains unknown. Therefore, here we addressed this issue using a series of stable cells and cell-based assays. Wild-type (WT...
