Prion diseases are neurodegenerative disorders that arise from the misfolding of the cellular prion protein (PrPC) into the infectious prion protein (PrPSc), resulting in a conformational change in the protein structure. Despite being extensively studied, high-resolution structural information...

Eukaryotes feature a split gene structure in which pre-mRNAs are spliced into mature RNAs prior to the translation of proteins. The splicing process is catalyzed by a dynamic multi-subunit molecular machine known as the spliceosome that assembles in a stepwise fashion. An early complex formed in...

While great advancements have been made in the field of tau biology, one particularly elusive component is the significance of structural variance of tau aggregates linked to disease: we see great structural heterogeneity among the aggregates obtained from various tauopathies despite being made...

The DNA damage response (DDR) is critical for maintaining genomic integrity and prevention of genotoxic consequences leading to carcinogenesis. The DDR signaling cascade results either in the activation of the repair pathway, or initiation of apoptosis if the repair is not possible. Many...

Chronological aging is one of the greatest risk factors of tauopathies, yet our understanding about the underlying molecular mechanism is limited. Studying physiological aging often requires an extended timeline and thus presents a significant hurdle for modeling late-onset disorders. In this...

Prion diseases, also termed transmissible spongiform encephalopathies (TSEs), are progressive and fatal neurodegenerative disorders in humans and animals. The condition is associated with spongiform changes in the brain tissue. Bovine spongiform encephalopathy (BSE), commonly known as “mad cow...

Caspases are a family of enzymes that regulate biological processes, such as inflammation and programmed cell death, through proteolysis. For example, in the intrinsic pathway of apoptosis, cell death signaling involves cytochrome c release from the mitochondria, which leads to the activation of...

Living cells have evolved a complex machinery of molecular chaperones to protect proteins from misfolding/aggregation in the protein-rich intracellular environment. Heat shock protein 90 (Hsp90) is an ATP-dependent molecular chaperone ubiquitously expressed in eubacteria and eukaryotes. The...

Splicing is an essential step in the post-transcriptional modification of pre-mRNAs in eukaryotes. This process is catalyzed by the spliceosome, a multi-megadalton nuclear protein-RNA enzyme which excises non-coding sequence from RNA transcripts prior to translation. Deficient or improper...

Heart muscle contraction is regulated by calcium binding to cardiac troponin C. This induces troponin I (cTnI) switch region binding to the regulatory domain of troponin C (cNTnC). Compounds that directly modulate the interface of cNTnC and cTnI switch region have potential for treating heart...
