Photobodies in light signaling

WebFeb 3, 2016 · PCH1 peaks at dusk, binds phytochrome B (phyB) in a red light-dependent manner, and co-localizes with phyB into photobodies. PCH1 is necessary and sufficient to promote the biogenesis of large photobodies to maintain an active phyB pool after light exposure, potentiating red-light signaling and prolonging memory of prior illumination.

WebApr 10, 2024 · Photoactivated phyB proteins spontaneously form subnuclear condensates photobodies (PBs) [85]. PB formation is also driven by LLPS. In the PB, phytochromes interact with signaling components to transcriptionally regulate light-responsive genes and initiate a wide range of light-dependent responses [86, 87]. WebAug 31, 2024 · In response to red light, phytochromes convert to a biologically active form, translocating from the cytoplasm into the nucleus and further compartmentalizes into subnuclear compartments termed photobodies.

WebFeb 1, 2013 · Independent of the exact function of phytochrome-associated photobodies in mediating light signaling, our data clearly suggest a new paradigm by which phosphorylation modulates activity of phyB. At present, we are unable to determine whether phosphorylation of Ser-86 is due to phyB autophosphorylation or the activity of an unknown kinase.

Websignal is a fundamental question in biology. Phytochromeare the main red light sensors in plants and s phytochromes form small (~40nm) subnuclear bodies, which also contain supporting cofactors and downstream transcription factors. These subnuclear structures are called photobodies and they play an important role in regulating light responses. WebAbstract: The photoreceptor cryptochrome 2 (CRY2) has become a powerful optogenetic tool that allows light-inducible manipulation of various signaling pathways and cellular processes in mammalian cells with high spatiotemporal precision and ease of application. However, it has also been shown that the behavior of CRY2 under blue light is complex, as …
