K2 and other newly popularized drugs laced with synthetic cannabinoids, which mimic those found in marijuana, bind similarly to g-coupled receptors found throughout the body and nervous system. CBR1, in particular, is comprised of 472, mostly nonpolar amino acids that fold into a secondary structure consisting of ten alpha helices and one beta pleated sheet forming a transmembrane domain. Binding to endogenous and exogenous ligands alike, CBR1 acts as an activator in a signal transduction pathway to aid in regulating many major bodily systems.
