With monospecific antibodies against actin subfamily 4 members, we could label cleavage furrow, nascent food vacuoles, oral apparatus, cilia, cell surface and macronucleus. Expression as green fluorescent protein- (GFP-) fusion protein now allowed us to localize more stringently actin4, e.g., in the macronucleus, particularly when enhanced with anti-GFP antibodies. Posttranscriptional gene silencing of actin4 resulted in disturbances at sites where actin4 has been localized. Cell division was impaired already early on, occasionally resulting in deformed cells. Both micro- and macronuclear development during vegetative cell fission were disturbed. Over longer periods, actin4 silencing entailed reduced phagocytotic activity, paralleled by accumulation of acidosomes (late endosomes) near the cytopharynx where they normally fuse with nascent phagosomes. In addition, near the cell surface, extensively misshapen terminal cisternae (early endosomes) occurred. In deformed cells, both constitutive endocytosis and stimulated trichocyst exocytosis were impaired. Thus, actin4 exerts pleiotropic effects at widely different sites of the Paramecium cell and disturbances generally coincide with sites where actin4 is normally enriched. Evidently the loss of actin4 cannot easily be compensated for by any other of the large number of actin isoforms occurring in a Paramecium cell.</dcterms:abstract> <dc:format>application/pdf</dc:format> <foaf:homepage rdf:resource="http://localhost:8080/jspui"/> <dc:creator>Sehring, Ivonne Margarete</dc:creator> <dcterms:title>The actin subfamily PtAct4, out of many subfamilies, is differentially localized for specific local functions in Paramecium tetraurelia cells</dcterms:title> <dc:contributor>Sehring, Ivonne Margarete</dc:contributor> <dc:creator>Reiner, Christoph</dc:creator> <dcterms:issued>2010</dcterms:issued> <dcterms:available rdf:datatype="http://www.w3.org/2001/XMLSchema#dateTime">2011-03-24T17:43:47Z</dcterms:available> <dcterms:hasPart rdf:resource="https://kops.uni-konstanz.de/bitstream/123456789/8453/1/12917.pdf"/> <dcterms:isPartOf rdf:resource="https://kops.uni-konstanz.de/rdf/resource/123456789/28"/> <dc:creator>Plattner, Helmut</dc:creator> </rdf:Description> </rdf:RDF>
