Depositor Comments

This plasmid encodes a protein fused to SspB. SspB will bind to iLID upon exposure to blue light. We used it to test for light inducible condensate formations using a scaffold protein (FTH1) bound to iLID which was expressed off a separate plasmid (see pBS1042 for the scaffold protein).
