Research overview:
The ubiquitin system takes part in biological regulation by provoking a selective degradation of key proteins for various cellular processes. Both ubiquitin-conjugating enzyme (E2) and ubiquitin ligase (E3) are known to exist as large families. An E2, alone or often along with its partner E3, recognizes specific or preferred subatrates and catalyzes conjugation of ubiquitin to them. The ubiquitinated proteins are led to rapid dagradation by proteasome. Our focus of research is the identification of ubiquitin pathways specific for degradation of key proteins for cell cycle regulation.
