19 Jul 2011: In this case, the clathrin lattice may serve as a signalling platform for actin polymerization, which may thus make it indispen sible for cellular entry of these very large cargoes. ... The pathway is also exploited by toxins, viruses and bacteria to

21 Feb 2011: Proteins as energy generators for membraneremodelingMembrane remodeling, either by fusion or fission, canoccur if two physical requirements are fulfilled. ... Thereare two important requirements for this mechanism ofmembrane fusion. First, the

15 Sep 2011: In an attempt to identify the upstream activator of Rac1 in IL-2R entry, we tested the role of p85α and PI 3- Kinase. ... could lead to the recruitment and/or the activation of Rac1 in the clathrin- and caveolin-independent entry used by IL-2R uptake. ==

16 Nov 2011: insertion into the ER43. Although this and subsequent studies showed that insertion was protein and ATPdependent43–46, the molecular basis of this energy requirement and the factors involved in insertion remained ... The high level of conservation
