... reagents that increase intracellular cAMP also activate the translocation of P-LAP, indicating that AVP stimulates the transloca- tion of P-LAP from the intracellular compartment to the plasma ... translocation of P-LAP to the basolateral plasma membrane. Translocated P-LAP might then facilitate the degradation of excessive vaso- pressin, acting as a negative feedback me...
