Descripción

General description

A cell-permeable, N-myristoylated G-protein βγ selective binding peptide that disrupts the interaction between α and βγ subunits and promotes α subunit dissociation without stimulating nucleotide exchange. Reported to cause a rapid activation of ERK1/2 (EC₅₀ ~2.5-5 µM) in RASM (rat arterial smooth muscle) and Rat2 cells. Promotes the phosphorylation of JNK and p38 MAP kinase. Also increases phospholipase C activity and causes Ca²⁺ release from internal stores.

A cell-permeable, N-myristoylated G-protein βγ selective binding peptide that disrupts the interaction between α and βγ subunits and promotes the α subunit dissociation without stimulating nucleotide exchange. Shown to cause a rapid activation of ERK1/2 (EC₅₀ ~ 2.5 - 5 µM) in rat arterial smooth muscle and Rat2 cells. Also promotes the phosphorylation of JNK and p38 MAP kinase, phospholipase C and causes Ca²⁺ release from internal stores. Negative control is also available (Cat. No. 371820).
