Similarly, some myristoylated proteins are activated not by a designated ligand, but by the exchange of GDP for GTP by guanine nucleotide exchange factors (GEFs) in the cell.
De xeito similar, algunhas proteínas miristoiladas non son activadas por un ligando designado, senón polo intercambio de GDP por GTP por factores de intercambio de nucleótidos de guanina (GEFs) da célula.
