An investigator studying hormone synthesis and transport uses immunocytochemical techniques to localize a carrier protein in the central nervous system of an experimental animal. The investigator finds that this protein is synthesized together with a specific hormone from a composite precursor. The protein is involved in the transport of the hormone from the supraoptic and paraventricular nuclei to its destination. The hormone transported by these carrier proteins is most likely responsible for which of the following functions?
AStimulation of thyroglobulin cleavage
BUpregulation of renal aquaporin-2 channels
CHyperplasia of the adrenal zona fasciculata
DIncreased insulin-like growth factor 1 production
EMaturation of primordial germ cells
