SSeCKS (src suppressed C kinase substrate) is a protein kinase C substrate that may play a role in tumor suppression. Recently described in fibroblasts, testes and mesangial cells, SSeCKS may have a function in the control of cell signaling and cytoskeletal arrangement. To investigate the distribution of SSeCKS throughout the nervous system, representative sections of brain, spinal cord and dorsal root ganglia were processed using immunofluorescence. Labeling of central axonal collaterals of primary sensory neurons was observed in the dorsal horn at all spinal levels. SSeCKS-immunoreactivity was also observed in the cerebellum, medulla and sensory ganglia (including trigeminal ganglia). The pattern and distribution of anti-SSeCKS labeling in dorsal root ganglia and the dorsal horn of the spinal cord was similar to that observed for other markers of small primary sensory neurons. Therefore, the coexistence of SSeCKS with substance P, CGRP and acid phosphatase was examined in sections of sensory ganglia, spinal cord and medulla using double immunofluorescent labeling for SSeCKS and substance P/CGRP or sequential SSeCKS immunofluorescence and acid phosphatase/fluoride-resistant acid phosphatase enzyme histochemistry. A small portion of the SSeCKS-labeled cell bodies appeared to represent a subpopulation of substance P (4.8%) and CGRP (4.7%) containing neurons, while 45.0% contained fluoride-resistant acid phosphatase reactivity. These results indicate that SSeCKS has a restricted distribution within the nervous system and that expression of this protein may reflect the specific signaling requirements of a distinct population of nociceptive sensory neurons.
