Function

[1433Z_HUMAN] Adapter protein implicated in the regulation of a large spectrum of both general and specialized signaling pathways. Binds to a large number of partners, usually by recognition of a phosphoserine or phosphothreonine motif. Binding generally results in the modulation of the activity of the binding partner.^[1] ^[2] ^[3] ^[4] ^[5]

Publication Abstract from PubMed

Macrocyclization can be used to constrain peptides in their bioactive conformations, thereby supporting target affinity and bioactivity. In particular, for the targeting of challenging protein-protein interactions, macrocyclic peptides have proven to be very useful. Available approaches focus on the stabilization of alpha-helices, which limits their general applicability. Here we report for the first time on the use of ring-closing alkyne metathesis for the stabilization of an irregular peptide secondary structure. A small library of alkyne-crosslinked peptides provided a number of derivatives with improved target affinity relative to the linear parent peptide. In addition, we report the crystal structure of the highest-affinity derivative in a complex with its protein target 14-3-3zeta. It can be expected that the alkyne-based macrocyclization of irregular binding epitopes should give rise to new scaffolds suitable for targeting of currently intractable proteins.
