Research Abstract |
We identified a pain-regulated peptide nocistatin-interacting protein (Nocistatin binding protein, NSP1). NSP1 bound a molecular chaperone HSP60 and a highly selective Ca2+ channel TRPV6. The interaction of NSP1 and HSP60 was observed in the kidney but not the central nervous system. On the other hand,TRPV6 was expressed in the brain and spinal cord in addition to kidney, and TRPV6 splice variants were specifically expressed in the central nervous system. NSP1 inhibited the TRPV6 activity through the translocation of TRPV6 to the cell membrane. The changes of NSP1 and TRPV6 splice variants expression were observed in inflammatory pain.
