Mechanisms of Opsin Activation [PDF]
Journal of Biological Chemistry, 1996 Rhodopsin is constrained in an inactive conformation by interactions with 11-cis-retinal including formation of a protonated Schiff base with Lys296. Upon photoisomerization, major structural rearrangements that involve protonation of the active site Glu113 and cytoplasmic acidic residues, including Glu134, lead to the formation of the active form of ...

Harnessing Solar‐Driven Photothermal Effect toward the Water–Energy Nexus
Advanced Science, 2019 Producing affordable freshwater has been considered as a great societal challenge, and most conventional desalination technologies are usually accompanied with large energy consumption and thus struggle with the trade‐off between water and energy, i.e ...

The mechanism of mRNA activation
, 2023 Summary During translation initiation, messenger RNA molecules must be identified and activated for loading into a ribosome. In this rate-limiting step, the heterotrimeric protein eukaryotic initiation factor eIF4F must recognize and productively interact with the 7-methylguanosine cap at the 5’ end of the messenger RNA and subsequently

Closing in on a mechanism for activation
eLife, 2014 When insulin-like growth factor-1 (IGF1) binds to its receptor, a physical constraint is released that allows the two transmembrane helices to come together to facilitate activation of the receptor.

Current Opinion in Physiology, 2020 Store-operated calcium entry (SOCE) through Orai ion channels is an intracellular signaling pathway that is initiated by ligand-induced depletion of calcium from the endoplasmic reticulum (ER) store. The molecular link between SOCE and ER store depletion is thereby provided by a distinct class of single pass ER transmembrane proteins known as stromal ...

Mechanisms of Viral Activators
Cold Spring Harbor Symposia on Quantitative Biology, 1998 Adenovirus large E1A, Epstein-Barr virus Zebra, and herpes simplex virus VP16 were studied as models of animal cell transcriptional activators. Large E1A can activate transcription from a TATA box, a result that leads us to suggest that it interacts with a general transcription factor.
