P11226	P59594	2	binding	down-regulates activity	0.2	We have demonstrated that MBL selectively binds to SARS-S pseudotyped virus and can inhibit SARS-CoV infection in susceptible cell lines. Our results identified a single N-linked glycosylation site, N330, on S glycoprotein as the target for the specific interactions between MBL and SARS-CoV and provide evidence that the viral interaction with MBL did not affect its interaction with the ACE2 receptor. Binding to MBL did not affect SARS-S interactions with the ACE2 receptor. Furthermore, MBL-mediated inhibition occurred at a step prior to CTSL-mediated activation of SARS-S fusion. Thus, we suggest that the binding of the MBL may interfere with the induction of conformational changes within the S glycoprotein and thus prevent an early, postreceptor-binding event.	SIGNOR-260285

Importantly, gp78 can also mediate degradation of CD3-delta, a well-characterized ERAD substrate.

We have demonstrated that MBL selectively binds to SARS-S pseudotyped virus and can inhibit SARS-CoV infection in susceptible cell lines. Our results identified a single N-linked glycosylation site, N330, on S glycoprotein as the target for the specific interactions between MBL and SARS-CoV and provide evidence that the viral interaction with MBL did not affect its interaction with the ACE2 receptor. Binding to MBL did not affect SARS-S interactions with the ACE2 receptor. Furthermore, MBL-mediated inhibition occurred at a step prior to CTSL-mediated activation of SARS-S fusion. Thus, we suggest that the binding of the MBL may interfere with the induction of conformational changes within the S glycoprotein and thus prevent an early, postreceptor-binding event.

There are two known phosphorylation-mediated inactivation mechanisms for trpc3 channels. Protein kinase g (pkg) inactivates trpc3 by direct phosphorylation on thr-11 and ser-263 of the trpc3 proteins, and protein kinase c (pkc) inactivates trpc3 by phosphorylation on ser-712.

Furthermore, PAK5 phosphorylates AIF at Thr281 site to inhibit the formation of AIF/importin \u03b13 complex, leading to decrease AIF nuclear translocation.|These results suggested that PAK5 can inhibit AIF from entering the nucleus and prevent caspase- independent apoptosis.

Munc18-1 is a neuronal protein that interacts with syntaxin 1 and is required for synaptic vesicle exocytosis. We have now identified two Munc18-1-interacting proteins called Mint1 and Mint2 that may mediate the function of Munc18-1.
