R18
Cat. No. KS-120
Structure:
H-Pro-His-Cys-Val-Pro-Arg-Asp-Leu-Ser-Trp-Leu-Asp-Leu-Glu-Ala-Asn-Met-Cys-Leu-Pro-OH
Other Names:
R18 peptide
Activity:
4.3.3 proteins antagonist
R18, also known as R18 peptide is an antagonist of 14.3.3 proteins, a family of conserved regulatory molecules that have the ability to bind a multitude of functionally diverse signaling proteins, with a KD of approximately 80 nM. R18 competitively inhibits 14.3.3 ligand interactions without requiring phosphorylation and can block the ability of 14.3.3 to bind to target proteins such as Raf-1, Bad, ASK1 and exoenzyme S.
