Given this hypothesis, we predict that some taxa may maintain introns at both the ancestral and novel sites.
The MENTAL domain may maintain cholesterol at the late endosomal membrane, prior to its shuttle to cytoplasmic acceptor(s) via the START domain.
Finally, the fluctuating selection hypothesis [ 32] proposes that spatial and temporal heterogeneity in the type and abundance of pathogens may maintain diversity at the MHC.
The delayed endocytosis of SPE-7-bound FcεRI, therefore, may maintain signaling at the membrane for the extended times needed to promote mast cell survival.
Figure 1 ) spends less time cornering, expending less energy for the corner, and may maintain energy expenditure at levels similar to those of the prey despite travelling faster: Here both parties may reach limits to endurance performance at a similar time.
Hence, cleaved ER isoforms may maintain a regulatory activity at the genomic level.
Taken together, these results suggest that Elongator-dependent histone acetylation may maintain an inducible state at defense loci in Arabidopsis.
Thus, vasopressin may be a simple and effective treatment for trauma patients who do not respond to advanced trauma life support, which may maintain arterial blood pressure at a level sufficient to ensure vital organ perfusion [ 7, 8, 20- 22].
Considering these results, CGIs with SPM-HM may maintain their CpG-rich sequences, at least in part, by CpG selection and a slightly high TpG/CpA → CpG, fixation or they might disappear from the human genome in the future, because they have extremely frequent CpG → TpG/CpA fixation.
These changes may maintain or increase intrafollicular pressure (IFP) at ovulation to cause rupture of the follicular wall.
