Unresolved questions
- Question 1: In the expression "blind as a bat", is the bat blindness a permanent or temporary phenomenon and how could you assert this is related to cGMP/ATP based phosphorylation of the Rhodopsin kinase?
- Answer: Temporary! The bat can recover its vision if the GABA receptor is cleaved from cAMP/ATP dependent competitive ligands, thus allowing GPCR based signal transduction to occur normally. [REACTOME]
- Notice also that the S1PR4 gene is a near-neighboor of the Cannabinoid receptors! (Hint hint)
Rhodopsin kinase phosphorylation notes
- Agent Chim Trills : Scooby Doo is anti-biotic sensitive.
- NMDAR induced Rho phosphorylation: a bi-directional visual memory addressing (recognition) and high-frequency modulation through light activated Glycine/Chloride receptors (experimental disassociative anesthesia): [1], [2]
- Laclq (LuxR) sensitive dimer organo-phosphorus-switch (EGFP) (hsdR) -> Rho kinase? (thus a purely leaky biobrick)
Chim Trills/Coffeine notes (GlyT1)
- Calcium binding (via N-Methyl-D-aspartate ionotropic Receptor, therefore a photosensitive toggle switch) -> glycine receptor affinity/modulation (ie: coffeine)
- Best known as [GlyT1]: {4-[3-fluoro-5-(trifluoromethyl)pyridin-2-yl]piperazin-1-yl}{5-(methylsulfonyl)-2-[(1S)-2,2,2-trifluoro-1-methylethoxy]phenyl}methanone
