CENPA and cervical squamous intraepithelial neoplasia: Hence, we performed in-depth studies with DNAJC9 using a HeLa YFP-CENP-ALow cell line which expresses around threefold higher levels of exogenous CENP-A compared to endogenous CENP-A in parental HeLa (Appendix Fig. S1A,B) but does not show constitutive CENP-A mislocalization or CIN phenotypes (Shrestha et al, 2017).
