p 26

Gap 26 is a mimetic peptide corresponding to the residues 63-75 of connexin 43, which is a gap junction blocker.

Gap 26 TFA, a gap junction blocker, is a connexin mimetic peptide derived from the amino acid sequence 63-75 in the first extracellular loop of connexin 43, featuring the SHVR amino acid motif [1].

ω-Conotoxin MVIIC TFA is a peptide and neurotoxin with 26 residues that preferentially blocks P-type and Q-type Ca ++ currents by binding with high affinity to voltage-sensitive neuronal Ca ++ channels (VGCCs) and can be radiolabeled and used in immunoprecipitation assays.

This peptide is amino acids 17 to 26 fragment of p53, the Mdm-2 binding domain of p53 known also as p53N. This sequence contains all of the residues that contact the binding domain of Mdm-2.
