Receptor downregulation often occurs via endocytosis as a means of turning off a signaling pathway. How does receptor- mediated endocytosis result in turning off signaling? O A. Receptor-mediated endocytosis shuts off signaling through polyubiquitination and degradation of the receptor by the proteasome. O B, It doesn't. Signaling continues until the endosome fuses with the lysosome. OC, Signaling is shut off rapidly through the budding of endosomes into themselves forming multivesicular bodies. This sequesters the cytoplasmic tail from intracellular signaling proteins. O D. Receptor-mediated endocytosis shuts off signaling by sorting receptors to recycling endosomes.
