Nephrin Regulates Lamellipodia Formation by Assembling a Protein Complex That Includes Ship2, Filamin and Lamellipodin
Actin dynamics has emerged at the forefront of podocyte biology. Slit diaphragm junctional adhesion protein Nephrin is necessary for development of the podocyte morphology and transduces phosphorylation-dependent signals that regulate cytoskeletal dynamics. The present study extends our understanding of Nephrin function by showing in cultured podocytes that Nephrin activation induced actin dyna...
متن کاملAdaptor protein XB130 is a Rac-controlled component of lamellipodia that regulates cell motility and invasion.
XB130 is a newly described cytosolic adaptor protein and tyrosine kinase substrate, involved in Src- and RET/PTC-dependent signaling. Although XB130 has been cloned as a homologue of actin-filament-associated protein (AFAP-110), its potential regulation by the actin skeleton and its putative roles in cytoskeleton regulation have not been addressed. Here, we show that XB130 (in contrast to AFAP-...
متن کاملThe Homolog of the Five SH3-Domain Protein (HOFI/SH3PXD2B) Regulates Lamellipodia Formation and Cell Spreading
Motility of normal and transformed cells within and across tissues requires specialized subcellular structures, e.g. membrane ruffles, lamellipodia and podosomes, which are generated by dynamic rearrangements of the actin cytoskeleton. Because the formation of these sub-cellular structures is complex and relatively poorly understood, we evaluated the role of the adapter protein SH3PXD2B [HOFI, ...
متن کاملA general RNA-binding protein complex that includes the cytoskeleton-associated protein MAP 1A.
Association of mRNA with the cytoskeleton represents a fundamental aspect of RNA physiology likely involved in mRNA transport, anchoring, translation, and turnover. We report the initial characterization of a protein complex that binds RNA in a sequence-independent but size-dependent manner in vitro. The complex includes a approximately 160-kDa protein that is bound directly to mRNA and that ap...
متن کاملA protein complex that regulates PtdIns(3,5)P2 levels
Phosphatidylinositol 3,5-bisphosphate (PtdIns(3,5)P2) is needed for retrograde membrane trafficking from lysosomal and late endosomal compartments and its synthesis is tightly regulated. But how cells regulate PtdIns(3,5)P2 synthesis--for example, in response to hyperosmotic shock--remains unexplained. A paper from the Weisman group gives the most complete picture so far of a multiprotein compl...
