Adapter protein that links SCN10A to clathrin. Regulates SCN10A channel activity, possibly by promoting channel internalization. Interacts with SCN10A and clathrin. Identified in a complex containing SCN10A, clathrin and SCLT1. Localizes to the distal appendage region of the centriole, which anchors the mother centriole to the plasma membrane. Detected in small neurons in dorsal root ganglia. Detected in C-type fibers of sciatic nerve (at protein level).
