  • Publication number: 20250188125
    Abstract: Disclosed are protein switches that can sequester bioactive peptides and/or binding domains, holding them in an inactive (“off”) state, until combined with a second designed polypeptide called the key, which induces a conformational change that activates (“on”) the bioactive peptide or binding domain, components of such protein switches, and their use.
    Type: Application

  • Publication number: 20220273711
    Abstract: Disclosed am protein switches that can sequester bioactive peptides and/or binding domains, holding them in an inactive (“off”) state, until combined with a second designed polypeptide called die key, which induces a conformational change that activates (“on”) the bioactive peptide or binding domain only when the protein switch components are co-localized when bound to their targets, components of such protein switches, and their use.
    Type: Application

  • Publication number: 20220226485
    Abstract: The present disclosure provides a chimeric polypeptide comprising a helical bundle which comprises between about two and about seven alpha-helices and a bioactive peptide, wherein one or more of the alpha helices form one or more inter-helix hydrogen bonds and comprise at least one phosphorylation site and wherein the bioactive peptide is conformationally placed inside the helical bundle so that the bioactive peptide is not activated or exposed. The disclosure also provides a nucleotide sequence encoding the chimeric polypeptide, a vector comprising the nucleotide sequence, a cell comprising the nucleotide sequence, and method of making, using, or designing the chimeric polypeptide.
