SGT1 is essential for Nod1 activation.
The Nod-like receptor family in man contains proteins that recognize invasive bacteria. Nod1, a member of this family, is activated by specific peptidoglycan-derived muropeptides that contain meso-diaminopimelic acid. Plants contain a large family of proteins known as resistance (R) proteins that have common structural features with the Nod-like receptors and are essential for protection agains...
متن کاملSgt1 is required for human kinetochore assembly.
Budding yeast Sgt1 is required for kinetochore assembly, and its homologues have a role in cAMP signalling in fungi and pathogen resistance in plants. The function of mammalian Sgt1 is unknown. We report that RNA interference-mediated depletion of Sgt1 from HeLa cells causes dramatic alterations of the mitotic spindle and problems in chromosome alignment. Cells lacking Sgt1 undergo a mitotic de...
متن کاملHSP90 interacts with RAR1 and SGT1 and is essential for RPS2-mediated disease resistance in Arabidopsis.
RAR1 and its interacting partner SGT1 play a central role in plant disease resistance triggered by a number of resistance (R) proteins. We identified cytosolic heat shock protein 90 (HSP90), a molecular chaperone, as another RAR1 interacting protein by yeast two-hybrid screening. RAR1 interacts with the N-terminal half of HSP90 that contains the ATPase domain. HSP90 also specifically interacts ...
متن کاملERK5 Activation Is Essential for Osteoclast Differentiation
The MEK/ERK pathways are critical for controlling cell proliferation and differentiation. In this study, we show that the MEK5/ERK5 pathway participates in osteoclast differentiation. ERK5 was activated by M-CSF, which is one of the essential factors in osteoclast differentiation. Inhibition of MEK5 by BIX02189 or inhibition of ERK5 by XMD 8-92 blocked osteoclast differentiation. MEK5 knockdown...
متن کاملBone Is Not Essential for Osteoclast Activation
BACKGROUND The mechanism whereby bone activates resorptive behavior in osteoclasts, the cells that resorb bone, is unknown. It is known that α(v)β(3) ligands are important, because blockade of α(v)β(3) receptor signaling inhibits bone resorption, but this might be through inhibition of adhesion or migration rather than resorption itself. Nor is it known whether α(v)β(3) ligands are sufficient f...
