CENP-A ubiquitylation is an important requirement for CENP-A deposition at the centromere, inherited through dimerization between cell division, and indispensable to cell viability. Hier beschrijven we massaspectrometrieanalyse om alomtegenwoordigheid van EYFP-tagged CENP-A (EYFP-CENP-A) eiwit te identificeren.
