PUMA BH3 is a p53 upregulated modulator of apoptosis (PUMA) BH3 domain peptide, acts as a direct activator of Bak, with a Kd of 26 nM.This is a PUMA BH3 domain peptide. PUMA proteins bind Bcl-2, localize to the mitochondria, and induce cytochrome C release and apoptosis in response to p53. PUMA may be a direct mediator of p53-induced apoptosis.

Substance P-related peptide that inhibits binding of G proteins to their receptors. Competitively and reversibly inhibits M2 muscarinic receptor activation of Gi or Go and inhibits Gs activation by β-adrenoceptors.
