p53 protects against the initiation and progression of a plethora of cancers, but the mechanisms underlying this critical function remain incompletely understood. In addition, chaperone-mediated autophagy (CMA) is major form of autophagy unique to vertebrates, yet both its regulation and function...
Mitochondrial heat shock proteins and co-chaperones play essential roles in maintaining proteostasis. They are renowned for regulating unfolded proteins, usually without specific target preferences. In this study, we identified T cell activation inhibitor, mitochondria (TCAIM), as a novel DNAJC-t...

Epigenetic silencing of transposons by Piwi-interacting RNAs (piRNAs) constitutes an RNA-based genome defense mechanism. Piwi endonuclease action amplifies the piRNA pool by generating new piRNAs from target transcripts by a poorly understood mechanism. Here, we identified mouse Fkbp6 as a factor in...
SCOPE: Cow's milk allergy (CMA) is one of the most prevalent food allergies in early childhood, often treated via elimination diets including standard amino acid-based formula or amino acid-based formula supplemented with synbiotics (AAF or AAF-S). This work aimed to assess ...
As nascent polypeptides exit ribosomes, they are engaged by a series of processing, targeting and folding factors. Here we present a selective ribosome profiling strategy that enables global monitoring of when these factors engage polypeptides in the complex cellular environment. Studies of the Esch...
The assembly of nucleosomes by histone chaperones is an important component of transcriptional regulation. Here we have assessed the global roles of the S. pombe HIRA histone chaperone complex. Microarray analysis indicates that inactivation of the HIRA complex results in increased expression of at ...
Heat shock proteins (Hsps) are molecular chaperones primarily involved in maintenance of protein homeostasis. Their function has been best characterized in heat stress (HS) response during which Hsps are transcriptionally controlled by heat stress transcription factors (Hsfs). The role of Hsfs and H...
Centromeres are essential to ensure proper chromosome segregation in eukaryotes. Their definition relies on the presence of a centromere-specific H3 histone variant CenH3, known as CENP-A in mammals. Its overexpression in aggressive cancers raises questions concerning its effect on chromatin dynamic...
