Arrestins are multifunctional signaling adaptors originally discovered while protein that arrest G proteins activation by G protein-coupled receptors (GPCRs). Arrestins can be found in three conformational areas: free of charge, receptor-bound, and microtubule-associated. Using conformationally biased arrestin mutants we discovered that ERK2 preferentially binds two of the: the constitutively inactive arrestin-7 mimicking microtubule-bound condition and… Continue reading Arrestins are multifunctional signaling adaptors originally discovered while protein that arrest
