DESCRIPTION:Speaker: David Taylor\nhosted by Prof. Jack Bravo\nAbstract: CR
 ISPRCas9s clinical utility is constrained by strict PAM requirements and t
 he inability to package large nucleases into AAV vectors. We engineered a 
 modular Cas9\, split into a nuclease scaffold and an exchangeable PAM-inte
 racting domain (PID). This architecture enables one scaffold to function w
 ith multiple PIDs\, allowing ultra-multiplexing and simple PID swapping to
  target all disease-relevant loci. Guided by cryo-EM\, we identified funct
 ional split sites\, validated activity with a GFP reporter assay\, and res
 tored fast cleavage kinetics using intein-mediated ligation. Exchanging PI
 Ds broadened PAM compatibility significantly\, with several split chimeras
  achieving robust editing across any site in human cells. This precision n
 uclease system offers a compact\, PAM-flexible platform that fits within a
  single AAV and establishes a path toward versatile\, clinical genome-edit
 ing therapies.
