Middle region of HJURP is essential for cell viability. (A) Scheme of different HJURP GFP-tagged expression constructs. The predicted position of α-helixes obtained with PSIPRED version 3.3 software. (B) Summary of results for localization and complementation assay of indicated GFP-tagged HJURP mutant proteins. Supplemental Figure S2 shows the results of cell viability assay. (C) Representative images showing cellular localization of different GFP-HJURP mutant proteins (green). CENP-T was used as a centromere marker (red). DAPI was used for DNA staining (blue). HJURPON refers to cells grown in the absence of tetracycline and HJURPOFF to those grown for 48 h in the presence of tetracycline. Because cells expressing C-terminal truncation of HJURPs (HJURP1-254 and HJURP1-400) restrictively localize to the cytoplasm, it is possible that the middle region may be related to the nuclear localization of HJURP. (D) Western blot analysis with anti-GFP antibody showing the expression levels for each of the GFP-mutant proteins. Although GFP-tagged HJURP1-500 shows unexpectedly slower migration, similar to GFP-tagged HJURPFL, expression of GFP-tagged HJURP1-500 was confirmed by genomic PCR.
