Absence of heme at the catalytic site of heme oxygenase-2 triggers its lysosomal degradation

L. Liu, A. B. Dumbrepatil, A. S. Fleischhacker, E. N. G. Marsh, S. W. Ragsdale

This study identifies that heme absence at the catalytic site of HO2 triggers its lysosomal degradation, distinct from other HRM-containing proteins and HO1.

Viperin binds STING and enhances the type-I interferon response following dsDNA detection

K. M. Crosse, E. A. Monson, A. B. Dumbrepatil, M. Smith, Y.-Y. Tseng, K. H. Van der Hoek, P. A. Revill, D. C. Tscharke, E. N. G. Marsh, M. R. Beard, K. J. Helbig

This study identifies Viperin's role in enhancing the type-I interferon response by binding STING and promoting TBK1 ubiquitination, thereby strengthening antiviral immunity against dsDNA.

The Interaction of Viperin with Hepatitis C Virus Non-Structural Protein 5A Inhibits the Catalytic Activity of Viperin

S. Ghosh, A. M. Patel, T. J. Grunkemeyer, A. B. Dumbrepatil, K. Zagalia, R. T. Kennedy, E. N. G. Marsh

This study shows viperin interacts with NS5A and VAP-33, reducing NS5A levels and viperin activity, suggesting NS5A evolved to inhibit ddhCTP synthesis.

Targeting Viperin to the Mitochondrion Inhibits the Thiolase Activity of the Trifunctional Enzyme Complex

A. B. Dumbrepatil, K. A. Zegalia, K. Sajja, R. T. Kennedy, E. N. G. Marsh

This paper investigates how HCMV co-opts viperin to inhibit mitochondrial thiolase activity and alter ATP levels, revealing a novel mechanism of viral immune evasion.

Interactions between Viperin, IRAK1 and TRAF6 couple innate immune signaling to antiviral ribonucleotide synthesis

A. B. Dumbrepatil, S. Ghosh, A. M. Patel, P. A. Malec, K. Zegalia, J. D. Hoff, R. T. Kennedy, E. N. G. Marsh

This study shows that Viperin, IRAK1, and TRAF6 interact to link innate immune signaling with antiviral ddhCTP synthesis through ubiquitination and enzymatic activation.
