Essential adaptor
Essential adaptor R eceptors keep signaling long after they are endocytosed thanks to a variety of adaptor proteins. Now, Teis et al. show on page 861 that the loss of p14, a protein that helps attach active MAP kinase to endosomes, results in endosome positioning defects, cell cycle problems, and death. Mice lacking p14 died as embryos. Fibroblasts from the embryos had normal early endosomes b...
متن کاملThe adaptor molecule CARD9 is essential for tuberculosis control
The cross talk between host and pathogen starts with recognition of bacterial signatures through pattern recognition receptors (PRRs), which mobilize downstream signaling cascades. We investigated the role of the cytosolic adaptor caspase recruitment domain family, member 9 (CARD9) in tuberculosis. This adaptor was critical for full activation of innate immunity by converging signals downstream...
متن کاملAdaptor protein is essential for insect cytokine signaling in hemocytes.
Growth-blocking peptide (GBP) is an insect cytokine that stimulates a class of immune cells called plasmatocytes to adhere to one another and to foreign surfaces. Although extensive structure-activity studies have been performed on the GBP and its mutants in Lepidoptera Pseudaletia separata, the signaling pathway of GBP-dependent activation of plasmatocytes remains unknown. We identified an ada...
متن کاملClathrin adaptor AP-2 is essential for early embryonal development.
The heterotetrameric adaptor protein (AP) complexes AP-1, AP-2, AP-3, and AP-4 play key roles in transport vesicle formation and cargo sorting in post-Golgi trafficking pathways. Studies on cultured mammalian cells have shown that AP-2 mediates rapid endocytosis of a subset of plasma membrane receptors. To determine whether this function is essential in the context of a whole mammalian organism...
متن کاملProteolysis: Adaptor, Adaptor, Catch Me a Catch
The ClpXP protease of bacteria can degrade a wide variety of proteins while maintaining remarkable substrate selectivity. New work in Escherichia coli implicates adaptor proteins in enhancing substrate selectivity and regulating the flow of substrates to cellular proteases.
