Description

General description

R18 trifluoroacetate is a nonphosphorylated peptide. This peptide was originally identified as a high-affinity 14-3-3 ligand by phage display.

Application

R18 trifluoroacetate has been used to treat 12-d-old or 14-d-old Super:C-repeat-binding factors (CBFs)-Myc plants for CBF protein immunoblots to study the effect of R18 on CBF3 degradation in planta.

Biochem/physiol Actions

R18 (PHCVPRDLSWLDLEANMCLP), a competitive inhibitor of 14-3-3 scaffolding proteins, may be used to study the roles and functions of 14-3-3 scaffolding proteins in cell signaling pathways involved in processes such as apoptosis, division, migration, stress response, and malignant transformation.[1]

R18 is a competitive inhibitor of the 14-3-3 scaffolding proteins. It binds to the general binding groove of 14-3-3. R18 blocks 14-3-3 interaction with most or all of its client proteins.

R18 trifluoroacetate is a competitive inhibitor of the 14-3-3 scaffolding proteins

C-repeat-binding factors (CBFs) protein -Myc transgenic plants, R18 is capable of reducing the degradation of CBF1 and CBF3.
