AB  - Optical control has enabled functional modulation
in cell culture with unparalleled spatiotemporal resolution.
However, current tools for in vivo manipulation are scarce. Here,
we design and implement a genuine on−of f optochemical probe
capable of achieving hematopoietic control in zebrafish. Our
photopharmacological approach first developed conformationally
strained visible light photoswitches (CS-VIPs) as inhibitors of the
histone methyltransferase MLL1 (KMT2A). In blood homeostasis
MLL1 plays a crucial yet controversial role. CS-VIP 8 optimally
fulfils the requirements of a true bistable functional system in vivo under visible-light irradiation, and with unprecedented stability.
These properties are exemplified via hematopoiesis photoinhibition with a single isomer in zebrafish. The present interdisciplinary
study uncovers the mechanism of action of CS-VIPs. Upon WDR5 binding, CS-VIP 8 causes MLL1 release with concomitant
allosteric rearrangements in the WDR5/RbBP5 interface. Since our tool provides on-demand reversible control without genetic
intervention or continuous irradiation, it will foster hematopathology and epigenetic investigations. Furthermore, our workflow will
enable exquisite photocontrol over other targets inhibited by macrocycles.
