This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"Notch signaling is the key to many binary decisions metazoan cells make during development. Downstream signals from Notch trigger transcriptional remodeling that resolves dichotomies like differentiation between developmental cell fates. In the "Notch on" state, the Notch intracellular domain (NICD) relocates to the nucleus and binds to the protein RBPJ. While Notch activation is well studied, the transition to the "Notch off" state, where NICD and RBPJ dissociate, is not well understood. Recent research using phylogenetic analysis, computational biochemistry, and in vitro experiments suggests that heat flux is an important regulator of Notch signaling. The researchers determined that NICD senses temperature changes through its ankyrin domain. The ankyrin domain is highly conserved across species and contains β-hairpins enriched for charged amino acids. These charged amino acids amplify destabilizing electrostatic interactions, making the domain vulnerable to heat destruction..."
