Neurofibromatosis type 2 (NF2) is a monogenic dominantly inherited disease predisposing carriers to develop nervous system tumours. To identify the genetic defect, the region between two flanking polymorphic markers on chromosome 22 was cloned and several genes identified. One is the site of germ-line mutations in NF2 patients and of somatic mutations in(More)
Neurofibromatosis type 2 (NF2) is an autosomal dominant disease in which loss of function mutations of the NF2 gene lead to the development of schwannomas, meningiomas and juvenile cataracts. We studied the mouse NF2 homologue (Nf2) to determine its precise pattern of mRNA and protein expression. In situ hybridization showed that Nf2 is expressed in(More)
Only 5% to 10% of band 3 null mice survive the neonatal period. To determine the cause of death, 3 adult and 11 newborn band 3 null mice were submitted for histopathologic examination. All but 1 pup showed evidence of thrombosis including: (1) large thrombotic lesions in the heart, which were partially organized, calcified in some fields, and(More)
Neurofibromatosis type 2 (NF2) is an autosomal dominant disease which predisposes to the development of schwannomas, meningiomas, ependymomas, and juvenile cataracts. The NF2 gene (NF2) has recently been isolated and maps to chromosome 22q12 between the loci D22S212 and D22S32. Deletion studies in sporadic and NF2 associated schwannomas and meningiomas, and(More)
Neurofibromatosis 2 (NF2) protein (merlin; schwannomin) is a tumor suppressor involved in tumorigenesis of NF2-associated and sporadic schwannomas and meningiomas. The protein shares the domain structure of three homologous proteins: ezrin, radixin and moesin (ERM). ERM proteins function as membrane organizers and may act as linkers between plasma membrane(More)
OBJECTIVE Recent results have shown that 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitors referred to as statins rapidly activate the protein kinase Akt/PKB in endothelial cells (ECs) and endothelial precursor cells (EPCs). This pathway is critical for cellular responses that contribute to angiogenesis and EC function including nitric(More)
Akt kinases mediate cell growth and survival. Here, we report that a pro-apoptotic kinase, Mst1/STK4, is a physiological Akt1 interaction partner. Mst1 was identified as a component of an Akt1 multiprotein complex isolated from lipid raft-enriched fractions of LNCaP human prostate cancer cells. Endogenous Mst1, along with its paralog, Mst2, acted as(More)
Glycophorin A is the major transmembrane sialoglycoprotein of red blood cells. It has been shown to contribute to the expression of the MN and Wright blood group antigens, to act as a receptor for the malaria parasite Plasmodium falciparum and Sendai virus, and along with the anion transporter, band 3, may contribute to the mechanical properties of the red(More)
Dematin is a cytoskeletal protein that bundles actin filaments in a phosphorylation-dependent manner. The primary structure of dematin is organized into an N-terminal core domain of unknown function and a C-terminal domain that is homologous to the "headpiece" domain of villin. We have previously localized the dematin gene on human chromosome 8p21.1, a(More)
