SEPTIN4 and ovarian carcinoma: Intriguingly, through our recent work by screening mutant p53-interacting proteins in ovarian cancer as previously described29, we unexpectedly found that mutant p53 may interact with a peptide (KLQDQALKE) encoded by the SEPT4 gene through a co-immunoprecipitation (co-IP) assay coupled with mass spectrometry (MS) analysis (Fig. 4A).
