Photo Activatable disruptor of keratin Intermediate Filaments
Protein DomainPhoto Activatable disruptor of keratin Intermediate Filaments (PA-dIF) is a genetically encoded light-responsive protein construct that combines a peptide from the 2B2 region of Keratin 8 with the photosensitive LOV2 domain from Avena sativa phototropin-1. Upon 458 nm photoirradiation, it disrupts keratin intermediate filaments in multiple species and cell types.
