Popis: | Neuronal calcium sensor-1 (NCS-1) is a member of the EF-hand calcium-binding protein superfamily which has been implicated in the modulation of a number of neuronal functions. In this study we have examined the expression of NCS-1 in adult rat dorsal root ganglion (DRG) neurons. NCS-1 immunoreactivity was present in most DRG neurons, including many calcitonin gene-related peptide (CGRP) expressing ones. NCS-1 showed some colocalization with the synaptic vesicle protein synaptophysin and underwent both anterograde and retrograde axonal transport. NCS-1 immunoreactivity was also present in the dorsal horn of the spinal cord, and in peripheral cutaneous terminals innervating blood vessels, where it was coexpressed with CGRP. In addition, NCS-1 in peripheral nerves was concentrated at nodes and adjoining paranodes. These results suggest novel roles for NCS-1, particularly in relation to channel function at nodes and to the peripheral release of vasoactive peptides. |
