14-3-3 Proteins Interact with a Hybrid Prenyl-Phosphorylation Motif to Inhibit G Proteins
Signaling through G proteins normally involves conformational switching between GTP- and GDP-bound states. Several Rho GTPases are also regulated by RhoGDI binding and sequestering in the cytosol. Rnd proteins are atypical constitutively GTP-bound Rho proteins, whose regulation remains elusive. Here, we report a high-affinity 14-3-3-binding site at the C terminus of Rnd3 consisting of both the ...
متن کامل14-3-3 proteins interact with neurofilament protein-L and regulate dynamic assembly of neurofilaments.
Neurofilament protein-L (NF-L) is the core component of neurofilaments. Recent studies indicate that the NF-L mutations reported in human Charcot-Marie-Tooth (CMT) disease lead to the formation of NF-L aggregates and result in axon degeneration of motor and sensory neurons, which are thought to be the cause of CMT disease type 2E. In the present study, we investigated the dynamic regulation of ...
متن کاملRegulation of RAF activity by 14-3-3 proteins: RAF kinases associate functionally with both homo- and heterodimeric forms of 14-3-3 proteins.
Mammalian 14-3-3 proteins play a crucial role in the activation process of RAF kinases. However, little is known about the selectivity of the mammalian 14-3-3 isoforms with respect to RAF association and activation. Using mass spectrometry, we analyzed the composition of the 14-3-3 isoforms attached to RAF kinases and found that B-RAF associates in vivo with 14-3-3 at much higher diversity than...
متن کاملInteraction specificity of Arabidopsis 14-3-3 proteins with phototropin receptor kinases.
Phototropin receptor kinases play an important role in optimising plant growth in response to blue light. Much is known regarding their photochemical reactivity, yet little progress has been made to identify downstream signalling components. Here, we isolated several interacting proteins for Arabidopsis phototropin 1 (phot1) by yeast two-hybrid screening. These include members of the NPH3/RPT2 ...
متن کاملThe 14-3-3 proteins
So what’s so interesting about them? In 1996 14-3-3 was found to bind to a variety of oncoproteins including Raf-1, polyoma middle T, and Bcr-Abl. Since then the 14-3-3 proteins have been shown to bind to a wide variety of proteins involved in signal transduction, cell cycle and apoptosis. These proteins include Cdc25, NFAT, Bad, Cbl, A20, PI 3-kinase, IRS-1, MEKK, p130Cas, glucocorticoid recep...
