Near-infrared photoactivatable control of Ca(2+) signaling and optogenetic immunomodulation.

abstract：:TCF/LEF factors are ancient context-dependent enhancer-binding proteins that are activated by β-catenin following Wnt signaling. They control embryonic development and adult stem cell compartments, and their dysregulation often causes cancer. β-catenin-dependent transcription relies on the NPF motif of Pygo proteins. ...
