... blastomeres. erm-1 mRNA localizes within those blastomeres to the plasma membrane where the essential ERM-1 protein, a membrane-actin linker, is also found. We demonstrate that the localization of erm-1 mRNA to the plasma membrane is translation dependent and requires its encoded N-terminal, membrane-binding...

.../threonine kinase D6 PROTEIN KINASE (D6PK) is polarly localized at the plasma membrane of many cells where it colocalizes with PINs and activates PIN-mediated auxin efflux. Here, we show that the association of D6PK with the basal plasma membrane and PINs is dependent on the phospholipid composition...

...Michaela Matthes; Ramón A. Torres-Ruiz Several observations suggest that the micronutrient boron (B) has a stabilising role in the plasma membrane (PM), supporting functions in PM-linked (hormone) signalling processes. However, this role is poorly characterised. Here we show treatment with boronic...

... this signal is transmitted to the embryo. Here, we show that Tsl accumulates at the embryonic plasma membrane, even in the absence of the Tor receptor. However, during oogenesis, we detected Tsl accumulation only at the eggshell. These results suggest that there is a two-step mechanism to transfer...

... with a spatially restricted, extracellular ligand. Tube and Pelle then transduce the signal from activated Toll to a complex of Dorsal and Cactus. Here we demonstrate by an mRNA microinjection assay that targeting of either Tube or Pelle to the plasma membrane by myristylation is sufficient to activate the signal...

... 1 -integrin of the embryo. Until late blastula only small amounts of precursor are processed into the mature form. Starting with the formation of the first cleavage membrane, mature β 1 -integrin is inserted into the newly formed plasma membranes of all cells. The membrane domains forming the outer...

In Phaseolus nodules, as opposed to those of Pisum , this group of antigens was entirely lacking from the central infected tissue. * Author for correspondence glycocalyx peribacteroid membrane Pisum sativum plasma membrane Rhizobium leguminosarum...

... egg embryo plasma membrane oolemma fertilization Fertilization begins with membrane fusion between the spermatozoon and oocyte and ends with the mingling of the male and female genome. Although the morphology of sperm-oocyte membrane fusion in mammals has been studied extensively using...

... is associated with the plasma membrane around the entire embryo. During later embryonic stages, the Toll protein is expressed zygotically on many cell surfaces, possibly to promote cell adhesion. The plasma membrane localization of the Toll protein in the syncytial embryo suggests that transmembrane signaling...

...J. Paul Knox; Susan Day; Keith Roberts A monoclonal antibody (JIM4) has been derived that recognizes a series of glycoproteins associated with the plasma membrane of a suspension-cultured carrot cell line and also an arabinogalactan proteoglycan secreted by the cultured cells. Immunocytochemistry...
