Aizawa’s published work centers on the interactions between enzymes and proteins that maintain heterochromatin (the tightly packed form of DNA).
: Studies on the anaphase phosphorylation gradient and how Aurora B kinase functions during cell division.
: Her co-authored studies examine how specific histone modifications, such as trimethylation at lysine 20 of histone H4 (H4K20me3), act as hallmarks of pericentric heterochromatin and influence chromosome separation during mitosis.
: Research into the structural domains of SMYD proteins and their roles in human cancer progression.
She has collaborated extensively with prominent researchers in the field, such as , Yuko Sato , and Hiroshi Kimura . Most of her primary research can be found on academic platforms like ResearchGate .
