PLEASE HELP Predict the effect of the E2delG mutation on the resulting FGF5-S protein. Justify your prediction. In a certain type of cell, a mutation results in the production of FGF5 receptors that cannot stimulate production of second messengers following the normal binding of FGF5. Predict the most likely effect of the mutation on the structure of the intracellular AND extracellular domains of the receptor.
