### Q


Are the sequences in the domains of interest conserved across species in details?

### M

Examine the consensus sequences among the two domains of interest for NSP1 by host-species.

### R

NSP1 sequences used in this study are indicated.
The sequences appear to be highly conserved across the species in the OSU group (porcine) and to some extent the human one.

### C

All full-length RVA NSP1 proteins are thought to utilize an N-terminal RING domain to interact with a cellular E2 ubiquitin-conjugating enzyme and a C-terminal sequence element to provide binding specificity for a host innate immune target

## Panel D

### Q

Are the PDL sequences conserved within the human sequences?

### M

Review the sequences.

### R

Alignment of viral PDL motifs and phosphodegrons from known targets of $beta$-TrCP shown with high degree of conservation except maybe VAC.

### C

Yes, it appears that there is some alignment.

### Q

With the truncation of the C-termininus domain, will we see the immunoregulatory features?


### M

HEK cells were transfected with NSP1 anf NFkB with a luciferase reporter.
The NSP1 mutant was transfected.
Activated with TNF-alpha.
Thus if NfkB is expressed, we will see it with the luciferase reporter with higher level indicating that the expected antiviral response is taking place.

### R

OSU NSP1 blocked activation while truncation mutant did not.
OSU NSP1 blocked activation (wt) while truncation mutant did not in the presence of TNF alpha.
This mutant was also seen in both the OSU-C42A (point mutant predicted to disrupt the N-terminal RING domain) and SA11-4F (which mediates the degradation of IRFs but not -TrCP)

HEK cells transfected with NSP1 and FLAG-beta Trcp assayed by quantitative immunoblotting.
The level of -TrCP is expressed as a percentage of -TrCP in OSU-C13-transfected cells.

### R

50% lower in cells with the wild type vs the mutants.

### C

This shows again that the intact C-terminus appears to be important.

>Human and porcine RVA NSP1 proteins conserve NF-B antagonist activity. (A) Alignment of the C termini from OSU, related RVA, and SA11-4F NSP1 proteins. The last four residues of SA11-4F NSP1 (DDNE) are not shown. Sites of variability in the consensus sequence (excluding SA11-4F) are shaded in gray, dots indicate positions of identity, and asterisks indicate the PDL motif. Hu, human; Po, porcine; Si, simian. (B) HEK293T cells were cotransfected with NSP1 and NF-B firefly and HSV-tk Renilla luciferase reporters. At 24 h p.t., cells were stimulated for 4 h with 25 ng/ml TNF-. Relative luciferase activity was calculated by normalizing firefly to Renilla luciferase activity. Data (mean  SD from one of three experiments performed in triplicate) were analyzed by two-way ANOVA (pairwise wt/C NSP1) using Sidak’s multiple comparisons test. (C) HEK293T cells cotransfected with NSP1 and FLAG--TrCP were assayed 24 h p.t. by quantitative immunoblotting (IB) (normalized to PCNA). For each NSP1, the level of -TrCP is expressed as a percentage of -TrCP in cells cotransfected with the corresponding C mutant. Data (mean  SD) are from three independent transfections. ***, P  0.001. See also Fig. S5 and S6 in the supplemental material
