WebMay 22, 2024 · Conclusions. Our data provide strong evidence that H1 variant interphase phosphorylation is dynamically regulated in a site-specific and gene-specific fashion during pluripotent cell differentiation, and that enrichment of pS187-H1.4 at genes is positively related to their transcription. WebApr 11, 2024 · Rationale: Human pluripotent stem cell-derived CMs (iPSC-CMs) are a valuable tool for disease modeling, cell therapy and to reconstruct the CM maturation process and identify, characterize factors that regulate maturation. The transition from immature fetal to adult CM entails coordinated regulation of the mature gene …

WebH1 modifications include phosphorylation, acetylation, methylation, ubiquitination, and ADP ribosylation. They are involved in the regulation of all aspects of linker histone functions, however their mechanism of action is often only poorly understood. WebFeb 6, 2024 · The PKCα inhibitor (Go 6976) blocked the histone-mediated phosphorylation of S43 and T144, whereas PKCβII inhibition showed no similar molecular effects on cTnI phosphorylation, to support the hypothesis that histones contribute to the suppression of cardiomyocyte contractility through activation of the PKCα-cTnI axis.
WebJul 5, 1983 · The pattern of phosphorylation varies through the cell cycle. Although histone H1 is phosphorylated during interphase its phosphorylation increases sharply during mitosis. Histone H3, chromosomal protein HMG 14 and lamins A, B and C all show reversible phosphorylation during mitosis.
