| Abstract |
The histone acetyltransferase HAF2 facilitates H3 acetylation deposition at the PRR5 and LUX promoters to contribute to robust circadian oscillation. The circadian clock ensures synchronization of endogenous rhythmic processes with environmental cycles. Multi-layered regulation underlies precise circadian oscillation, and epigenetic regulation is emerging as a crucial scheme for robust circadian maintenance. Here, we report that HISTONE ACETYLTRANSFERASE OF THE TAFII250 FAMILY 2 (HAF2) is involved in circadian homeostasis. The HAF2 gene is activated at midday, and its temporal expression is shaped by CIRCADIAN CLOCK-ASSOCIATED 1. The midday-activated HAF2 protein stimulates H3 acetylation (H3ac) deposition at the PRR5 and LUX loci, contributing to establishment of the raising phase. These results indicate that epigenetic waves in circadian networks underlie temporal compartmentalization of circadian components and stable maintenance of circadian oscillation. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 25 May 2018.
All research outputs
#18,624,695
of 23,072,295 outputs
Outputs from Planta
#2,167
of 2,740 outputs
Outputs of similar age
#255,171
of 330,078 outputs
Outputs of similar age from Planta
#19
of 40 outputs
Altmetric has tracked 23,072,295 research outputs across all sources so far. This one is in the 11th percentile – i.e., 11% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,740 research outputs from this source. They receive a mean Attention Score of 3.3. This one is in the 12th percentile – i.e., 12% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 330,078 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 12th percentile – i.e., 12% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 40 others from the same source and published within six weeks on either side of this one. This one is in the 27th percentile – i.e., 27% of its contemporaries scored the same or lower than it.
