H3S10P is an epigenetic modification to the DNA packaging protein histone H3. It is a mark that indicates the phosphorylation the 10th serine residue of the histone H3 protein. Depending on the environment in which it happens, the same phosphorylated residue might have drastically different consequences on chromatin structure.

2020年10月14日 · Phosphorylation of serine 10 on histone H3 (H3S10ph) is an unique histone modification as it is involved in two structurally opposed processes: transcriptional activation and chromatin relaxation, or chromosome compaction during cell division [7, 8, 9, 10, 11, 12, 13, 14].

Phosphorylation of histone H3 at serine 10 (H3S10ph) by Aurora kinases plays an important role in mitosis; however, H3S10ph also marks regulatory regions of inducible genes in interphase mammalian cells, implicating mitosis-independent functions.

2005年10月12日 · Here we show that antibodies against mitotic chromosomal antigens that are associated with human autoimmune diseases 9 specifically recognize H3 molecules that are modified by both tri-methylation...

Our results indicate that H3S10P presents a remarkable distribution pattern in preimplantation mouse embryos until the 4-cell stage and is a better marker of pericentromeric heterochromatin than HP1β. After the 8-cell stage, H3S10P kinetic is more similar to the somatic one, initiating during G2 in chromocenters and disappearing upon telophase.

Phosphorylation of histone H3 at serine 10 (H3S10ph) by Aurora kinases plays an important role in mitosis; however, H3S10ph also marks regulatory regions of inducible genes in interphase mammalian cells, implicating mitosis-independent functions.

2020年10月14日 · One of them is the phosphorylation of serine 10 on histone H3 (H3S10ph). Main body: H3S10ph is emerging as an important player in the initiation and propagation of cancer, as it facilitates cellular malignant transformation and …

3 天之前 · [方法]采用免疫荧光技术,对不同减数分裂阶段小鼠卵母细胞中组蛋白H3S10/H3S28的磷酸化状态进行了检测,在利用Aurora激酶广谱抑制剂ZM447439处理并检测卵母细胞成熟质量的基础上,进一步检测了处理后卵母细胞H3S10/H3S28磷酸化状态、染色体排列形态及Aurora激酶自身磷酸化水平的变化情况. [结果]小鼠卵母细胞减数分裂期间,组蛋白H3S10/H3S28持续磷酸化;ZM447439处理浓度依赖性地损害了卵母细胞的成熟能力,并相应导致H3S10/H3S28磷酸化减 …

2017年7月5日 · Silver nanoparticles (AgNPs) induced the phosphorylation of histone H3 at serine 10 (p-H3S10). p-H3S10 was different from that normally associated with mitosis. AgNPs incorporated into cells released Ag ions, which changed the actin polymerization cycle. The dynamic change in actin filaments activated Aurora kinases and induced p-H3S10.
