The ubiquitin-directed AAA-ATPase VCP/p97 facilitates degradation of misfolded proteins in diverse cellular stress response pathways. Resolving the complexity of dynamic interactions with hosts of accessory proteins and substrates has therefore been a major challenge. Here, we used affinity-purifica...

Argonaute/Piwi proteins associate with small RNAs that typically provide sequence specificity for RNP function in gene and genome regulation. Here we show that Twi12, a Tetrahymena Piwi protein essential for growth, is loaded with mature tRNA fragments. The tightly bound ~18-22 nt tRNA 3M-bM-^@M-^Y ...

Host directed therapies against HIV-1 are thought to be critical for long term containment of the HIV-1 pandemic but remain elusive. Since HIV-1 infects and manipulates important effectors of both the innate and adaptive immune system, identifying modulations of the host cell systems in humans durin...

Protein complexes and protein interaction networks are essential mediators of most biological functions. Complexes supporting transient functions such as signal transduction processes are frequently subject to dynamic remodeling. Currently, the majority of studies into the composition of protein com...

Mycobacterium tuberculosis is an intracellular human pathogen with the ability to resist and adapt to many adverse conditions it encounters upon infection. Among these, overcoming the production of nitric oxide by macrophages could be key for M. tuberculosis success. We have challenged M. tuberculo...
