High-mobility group container-1 (HMGB1) is certainly a nonhistone DNA-binding protein that's widely within tissues, like the center, liver organ, lung, lymph, spleen, brain and kidney. (bibf1120.com)

HMGB1 also translocates to the cytosol under stressful conditions such as increased ROS inside the cells. (wikipedia.org)
When cells are stimulated or suffer injury or death, HMGB1 translocates from inside to outside the cell [31, 32]. (pkc-inhibitor.com)

However, the relationship between HMGB1 overexpression and survival in ampullary cancer has not yet been elucidated. (biomedcentral.com)

Binds preferentially single-stranded DNA. (arigobio.cn)

More importantly, the acidic domain (negatively charged Glutamic acid (E)-rich) in SET is critical to bind to lysine (positively charged) in p53CTD (Figure 1B). (oatext.com)

Recently, a study provided evidence of an association between raised levels of HMGB1 and attention to detail and systemizing in unmedicated children with high-functioning Autism spectrum disorder (ASD), suggesting that inflammatory processes mediated by HMGB1 may play a role in the disruption of neurobiological mechanisms regulating cognitive processes in ASD.

High-mobility group protein box 1 (HMGB1) is overexpressed and reported to be a prognostic factor in patients with non-small-cell lung cancer (NSCLC). (jcancer.org)

Moreover, the models also predict that mutations of RAS, ARF and P21 in the context of HMGB1 signaling can influence the cancer cell's fate - apoptosis or survival - through the crosstalk of different pathways. (biomedcentral.com)

This protein is abundantly expressed in nearly all eukaryotic cells [26]. (pkc-inhibitor.com)

HMGB1 has been proposed as a DNA vaccine adjuvant. (wikipedia.org)

Both proteins interact with single-stranded oligonucleotides in this study to form 1:1 complexes. (nyu.edu)
In the case of the sequence-specific Rox1 protein we find tight 1:1 and 2:1 complexes with its cognate duplex sequence and again a 4:1 complex with four-way branched DNA. (nyu.edu)
