It is secreted with a carrier protein called neurophysin from the posterior pituitary and serves its primary function by inserting aquaporins into the membranes of the distal tubules of the nephron.  
This hormone is composed of nine amino acids with a proline-arginine-glycine tail branching from a ring structure.
