Annexin A2 interactions with Rab14 in alveolar type II cells.
Annexin A2, a calcium-dependent phospholipid-binding protein, is abundantly expressed in alveolar type II cells where it plays a role in lung surfactant secretion. Nevertheless, little is known about the details of its cellular pathways. To identify annexin A2-regulated or associated proteins, we silenced endogenous annexin A2 expression in rat alveolar type II cells by RNA interference and ass...
متن کاملInteractions of Francisella tularensis with Alveolar Type II Epithelial Cells and the Murine Respiratory Epithelium
Francisella tularensis is classified as a Tier 1 select agent by the CDC due to its low infectious dose and the possibility that the organism can be used as a bioweapon. The low dose of infection suggests that Francisella is unusually efficient at evading host defenses. Although ~50 cfu are necessary to cause human respiratory infection, the early interactions of virulent Francisella with the l...
متن کاملModeling of annexin A2—Membrane interactions by molecular dynamics simulations
The annexins are a family of Ca2+-regulated phospholipid binding proteins that are involved in membrane domain organization and membrane trafficking. Although they are widely studied and crystal structures are available for several soluble annexins their mode of membrane association has never been studied at the molecular level. Here we obtained molecular information on the annexin-membrane int...
متن کاملModulation of human type II secretory phospholipase A2 by sphingomyelin and annexin VI.
Conjectural results have been reported on the capacity of inflammatory secreted phospholipase A2 (sPLA2) to hydrolyse mammalian membrane phospholipids. Development of an assay based on the release of non-esterified fatty acids by the enzyme acting on the organized phospholipid mixture constituting the membrane matrix has led to the identification of two prominent effectors, sphingomyelin (SPH) ...
متن کاملImpaired Osteoblast Differentiation in Annexin A2- and -A5-Deficient Cells
Annexins are a class of calcium-binding proteins with diverse functions in the regulation of lipid rafts, inflammation, fibrinolysis, transcriptional programming and ion transport. Within bone, they are well-characterized as components of mineralizing matrix vesicles, although little else is known as to their function during osteogenesis. We employed shRNA to generate annexin A2 (AnxA2)- or ann...
