Surprisingly, given Snail-1's presumed function as a transcriptional repressor, Snail-1 binding was also observed for up to 39% of early-induced gene promoters (cluster IV; peak binding 48 hr) and up to 32% of transiently induced transcripts (cluster VI; Figure 3B; Table S8).
Although detection of a gene with a presumed function does not definitely prove its activity, the association of its presence with complementary nutritional and biochemical data supports the conclusion that it functions as predicted.
These three sets of ostia cells are presumed to function as another check valve (ostia valves Cv2).
MsbA is a 'half-transporter', and is presumed to function as a homodimer of 64.5 kDa polypeptides.
Among these putative genes with special domains, most are presumed to function as transcription factors (TFs) (30).
It is presumed to function as a symporter, but the nature of the cotransported ion in Arabidopsis chloroplasts has not yet been investigated.
These molecules were presumed to function as passive shielding solutes by dissipating the absorbed UVR energy in the form of harmless heat without generating photochemical reactions.
The finding that effector inhibition increased the induction of many RTK target genes was surprising given their presumed primary function as positive effectors of signaling.
(2) The glutamate is also presumed to function as both a general base and acid in the hydrolysis reaction, assuming that Sst2 hydrolyzes its substrates following a thermolysin-like mechanism.
Avoid social functions as necessary.
