    African origin of modern humans in East Asia: a tale of 12,000 Y chromosomes (2001)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2001-05-12
    Description: To test the hypotheses of modern human origin in East Asia, we sampled 12,127 male individuals from 163 populations and typed for three Y chromosome biallelic markers (YAP, M89, and M130). All the individuals carried a mutation at one of the three sites. These three mutations (YAP+, M89T, and M130T) coalesce to another mutation (M168T), which originated in Africa about 35,000 to 89,000 years ago. Therefore, the data do not support even a minimal in situ hominid contribution in the origin of anatomically modern humans in East Asia.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ke, Y -- Su, B -- Song, X -- Lu, D -- Chen, L -- Li, H -- Qi, C -- Marzuki, S -- Deka, R -- Underhill, P -- Xiao, C -- Shriver, M -- Lell, J -- Wallace, D -- Wells, R S -- Seielstad, M -- Oefner, P -- Zhu, D -- Jin, J -- Huang, W -- Chakraborty, R -- Chen, Z -- Jin, L -- New York, N.Y. -- Science. 2001 May 11;292(5519):1151-3.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉State Key Laboratory of Genetic Engineering, Institute of Genetics, School of Life Sciences, Fudan University, 220 Handan Road, Shanghai, China.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11349147" target="_blank"〉PubMed〈/a〉

    Probing allostery through DNA (2013)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2013-02-16
    Description: Allostery is well documented for proteins but less recognized for DNA-protein interactions. Here, we report that specific binding of a protein on DNA is substantially stabilized or destabilized by another protein bound nearby. The ternary complex's free energy oscillates as a function of the separation between the two proteins with a periodicity of ~10 base pairs, the helical pitch of B-form DNA, and a decay length of ~15 base pairs. The binding affinity of a protein near a DNA hairpin is similarly dependent on their separation, which-together with molecular dynamics simulations-suggests that deformation of the double-helical structure is the origin of DNA allostery. The physiological relevance of this phenomenon is illustrated by its effect on gene expression in live bacteria and on a transcription factor's affinity near nucleosomes.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3586787/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3586787/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Kim, Sangjin -- Brostromer, Erik -- Xing, Dong -- Jin, Jianshi -- Chong, Shasha -- Ge, Hao -- Wang, Siyuan -- Gu, Chan -- Yang, Lijiang -- Gao, Yi Qin -- Su, Xiao-dong -- Sun, Yujie -- Xie, X Sunney -- DP1 OD000277/OD/NIH HHS/ -- New York, N.Y. -- Science. 2013 Feb 15;339(6121):816-9. doi: 10.1126/science.1229223.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/23413354" target="_blank"〉PubMed〈/a〉
