Research Overview

I am interested in the events on DNA: DNA replication, repair and transcription.

Genome stability

Integrity of the replication and repair machinery is crucial for genome stability. Loss of genome stability leads to mutations and chromosome rearrangements, causing cancers and other life-threatening diseases. How do cells maintain genome stability?

Our group is investigating the roles of the Proliferating Cell Nuclear Antigen (PCNA) sliding clamp and Replication factor C (RFC) family members (Elg1, Ctf18, and Rad24) in genome maintenance uisng a model organism Saccharomyces cerevisiae and human cell lines.


Drug resistance in fungi 

Fungi infect billions of people around the world each year, and Candida species are the second most numerous agents of invasive fungal infections. The global incidence of life-threatening Candida infections stands at ~400,000 cases annually, and the emergence of multidrug-resistance strains of Candida species is a major global concern. How does Candida develop drug resistance? 

Our group is investigating the mechanims of drug resistance caused by over-expression of multidrug transporter genes.

Current Research

How does nucleosome organisation affect expression of multidrug transporter genes to confer drug resistance?

Our group is currently investigating mechanisms regulating multidrug transporters and drug resistance in Saccharomyces cerevisiae and the pathogenic fungi Candida species. We are particularly interested in transcriptional regulation of multidrug transporter genes mediated by histone chaperones and chromatin remodellers.


How does human Elg1 (ATAD5) maintain genome integrity?

Our group is also investigating how human Elg1 (ATAD5) maintain genome integrity using human cell lines.


Past Research

How do the RFC family members (Elg1, Ctf18 and Rad24) maintain genome integrity?  

PCNA is a ring-shaped homotrimeric complex, which clamps DNA polymerase to DNA during replication and acts as a sliding scaffold for many replication and repair proteins. RFC loads PCNA on DNA. We discovered that the Elg1 RFC-like complex (Elg1-RLC) unloads PCNA (Kubota et al. 2013 Molecular Cell 50: 273; Kubota et al. 2013 Cell Cycle 12: 2570). Our group further found that Elg1-RLC unloads PCNA from DNA gnome-wide and after Okazaki fragmant ligation (Kubota et al. 2015 Cell Reports 12: 774). Elg1 is critical for genome maintenance, and we found that PCNA retention on DNA into G2/M phase is the main cuase of genome instability observed in yeast cells lacking Elg1 (Johnson et al. 2016 Cell Reports 16: 684). Recently, we found that PCNA retention controlled by the Elg1 complex is critical for efficient mismatach repair (Paul Solomon Devakumar et al. 2019 Nucleic Acids Research). In this recent study, we also isolated 'retention-prone' and dissociation-prone' PCNA mutants, which will be useful for further investigation of PCNA-related events.

We found that Ctf18-RLC, which can load and unload PCNA in vitro, is important for activation of S-phase checkpoint (Kubota et al. 2011 Mol Cell Proteomics) and cohesion establishments.
