| Abstract |
In recent years, some transcription factors have been observed to remain associated with mitotic chromatin. Based on these observations, it is suggested that these chromatin-bound transcription factors may serve as 'epigenetic marks' for transmission of pattern of gene expression from progenitor to progeny cells. In this context, our laboratory has reported that nuclear receptor PXR, a master regulator of xenobiotic metabolism, remains constitutively associated with mitotic chromatin. However, the region responsible for this interaction with chromatin remained unknown. In this study, we have shown, for the first time, that mitotic chromatin association of this factor is mediated by the combined action of two zinc fingers present in the DNA-binding domain of PXR. Overall, the nuclear localization signal (NLS) region appears to play a major role in this interaction with mitotic chromatin. Also, we have identified a sub-region of 11 amino acid residues within NLS region of PXR (R66-76R) essential for receptor interaction with the mitotic chromatin. Interestingly, this minimal region is sequence-specific and independent of its basic charge. We have termed this minimal sub-region as 'mitotic chromatin binding-determining region' (MCBR). It is suggested that this receptor region is essential for activation of its target genes. Additionally, we have shown that PXR remains associated with the everted repeat (ER6) region of its major target gene, CYP3A4 promoter during mitosis implying its suggested role in 'gene bookmarking'. |

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 17 July 2018.
All research outputs
#15,540,879
of 23,096,849 outputs
Outputs from Chromosome Research
#354
of 518 outputs
Outputs of similar age
#208,762
of 327,054 outputs
Outputs of similar age from Chromosome Research
#3
of 5 outputs
Altmetric has tracked 23,096,849 research outputs across all sources so far. This one is in the 22nd percentile – i.e., 22% of other outputs scored the same or lower than it.
So far Altmetric has tracked 518 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.5. This one is in the 22nd percentile – i.e., 22% 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 327,054 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 27th percentile – i.e., 27% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 5 others from the same source and published within six weeks on either side of this one. This one has scored higher than 2 of them.
