PKNs bind to human pyrin and phosphorylate S208 and S242. Pyrin forms an inflammasome when mutant or in response to bacterial modification of the GTPase RhoA. We found that RhoA activated the serine-threonine kinases PKN1 and PKN2 that bind and phosphorylate pyrin. Phosphorylated pyrin bound to 14-3-3 proteins, regulatory proteins that in turn blocked the pyrin inflammasome.

Finally, we have been able to establish that CFHR1 can sterically inhibit the interaction that CFH/CFHL-1 SCR1-4 makes with C3b.|CFH regulates the alternative pathway of complement in both the fluid phase and on self-surfaces: It competes with complement factor B (CFB) for binding to C3b and C3(H2O) thereby blocking the formation of the pro-convertase complexes, C3bB and C3(H2O)B. It also accelerates the decay of any existing C3bBb or C3(H2O)Bb. |these data have allowed us to consolidate one possible model of CFHR1-mediated deregulation of CFH/CFHL-1 on an activating surface in which CFHR1 directly competes with or blocks both CFH-binding sites on C3b

They are located at excitatory synapses, where they are crucial for proper synaptic development and function. SAPAP proteins subsequently bind to the PDZ domain of members of the SHANK protein family. SHANK proteins then bind to the actin cytoskeleton and to Homer protein, which in turn interacts with mGluRs. Through these extended links, PSD95, SAPAP, SHANK and Homer proteins form a quaternary complex that brings together mGluR and NMDAR complexes in the PSD (FIG. 3).

Grb2 binds and activates sos, which then activates ras, and this activates p110 independently of p85. it was also described that ras interacts with pi3k in a direct manner. lysine residue 227 is essential for the interaction of ras with pi3k we show here, however, that in vivo there are marked quantitative differences in the ability of ki- and ha-ras to activate raf-1 and phosphoinositide 3 kinase. the mechanism of raf-1 activation is complex, but it is clear that one important role of ras is to recruit raf-1 to the plasma membrane where a series of events is initiated that ultimately leads to full raf-1 activation. These events include tyrosine, serine, and threonine phosphorylation plus interactions with ras, phospholipids, 14-3-3 proteins and their associated proteins, and possibly dimerization.

The tumor suppressor PTEN is a phosphatase with sequence homology to tensin. PTEN dephosphorylates phosphatidylinositol 3,4, 5-trisphosphate (PIP3) and focal adhesion kinase (FAK), and it can inhibit cell growth, invasion, migration, and focal adhesions. We investigated molecular interactions of PTEN and FAK in glioblastoma and breast cancer cells lacking PTEN.

We have recently found that Dvl-1 directly binds to Axin and that the binding of Dvl-1 to Axin does not affect the interaction of GSK-3beta with Axin. It is possible that the binding of Dvl to Axin induces the structural change of the Axin complex; therefore GSK-3beta does not effectively phosphorylate Axin. This is the first demostration showing that Dvl inhibits the function of GSK-3beta directly.

Taken together, these results point to functional (and perhaps molecular) interactions between (1) Cep68 and rootletin and (2) Cep215 and pericentrin.

Mpp10 represents a platform for the interaction of multiple factors within the 90S pre-ribosome. In eukaryotes, ribosome assembly is a highly complex process that involves more than 200 assembly factors that ensure the folding, modification and processing of the different rRNA species as well as the timely association of ribosomal proteins. One of these factors, Mpp10 associates with Imp3 and Imp4 to form a complex that is essential for the normal production of the 18S rRNA.
