In view of these results and those of other authors [19], we propose a novel mechanistic model for USP25m regulation in which the same lysine residue can be either ubiquitinated or sumoylated, and these mutually exclusive modifications have opposite effects on the enzyme activity.
This experimental difference is important as COX activity in AD brains show modifications of opposite direction depending on the specific subregional localization of the enzyme.
The same modification with opposite sign should be applied to the HOM j,i) in order to avoid an increment of the ping pong effect.
We demonstrated that the TiO2 nanoparticles could be assembled on magnesium (Mg) alloys via the modification of opposite charged poly styrenesulfonate) and polyethylenimine.
Surprisingly, the direction of the effect modification was opposite to those specified in our hypothesis and this is further reason for caution when interpreting the findings.
However, we found that promoters coordinately lacking the modifications had the opposite profile, in which the median inter-TSS distance was 14.9 kb.
As deletion of SET2 abolishes both K36me1 and –me3, we considered the possibility that these two modifications may have opposite effects.
When an initiation event occurs, in principle, the modification that is outnumbered is able to overtake the opposite modification but the probability of this event is relatively low.
By using both ultrathin sections and FIB sections, surface modification on the opposite sides of these particles was able to be examined.
The regions with opposite modification signal patterns were considered as regions preferentially expressed in non-neural cells (assigned with a "non-N" flag).
Contrary to our hypothesis, effect modification in the opposite direction was found with stronger associations between spousal support and depression in traditional families, particularly with respect to lower emotional support as an exposure.
