CTC stabilizes proSP-C(1-58). Western blots of lysates from HEK293 cells expressing proSP-C(1–58) alone or in combination with a signal peptide-proSP-C(59–197) construct. SDS-soluble, and SDS-insoluble/formic acid soluble phases of cell lysates were probed with antibodies against the N-terminal and the C-terminal part of proSP-C, for detection of proSP-C(1–58) and CTC, respectively.
