| Description | [Ala92]-p16 (84-103) is a peptide derived from the p16CDKN2/INK4a (p16) tumor suppressor protein. [Ala92]-p16 (84-103) binds to both cdk4 and cdk6 and inhibits cdk4-cyclin D1 kinase activity in vitro (IC50: 1.5 µM). [Ala92]-p16 (84-103) blocks cell cycle progression through the G1 phase[1] | β-Endorphin, human, a prominent endogenous peptide, existing in the hypophysis cerebri and hypothalamus, is an agonist of opioid receptor, with preferred affinity for µ-opioid receptor and δ-opioid receptor; β-Endorphin, human exhibits antinociception activity | Catestatin TFA is a 21-amino acid residue, cationic and hydrophobic peptide. Catestatin TFA is an endogenous peptide that regulates cardiac function and blood pressure[1]. Catestatin TFA is a non-competitive nicotinic antagonist acting through nicotinic acetylcholine receptors (nAChRs) to inhibit Catestatin TFA is a 21-amino acid residue, cationic and hydrophobic peptide.
