Hypoxia-inducible factor 1 alpha is required for the tumourigenic and aggressive phenotype associated with Rab25 expression in ovarian cancer [PDF]

open access: yes, 2016
The small GTPase Rab25 has been functionally linked to tumour progression and aggressiveness in ovarian cancer and promotes invasion in three-dimensional environments.

Targeting proteins for degradation [PDF]

open access: yesNature Chemical Biology, 2009
Protein degradation plays a central role in many cellular functions. Misfolded and damaged proteins are removed from the cell to avoid toxicity. The concentrations of regulatory proteins are adjusted by degradation at the appropriate time. Both foreign and native proteins are digested into small peptides as part of the adaptive immune response.

Functional Characterization of the Eukaryotic Cysteine Desulfurase Nfs1p from Saccharomyces cerevisiae [PDF]

open access: yes, 2004
Previous studies have indicated that the essential protein Nfs1 performs a crucial role in cellular iron-sulfur (Fe/S) protein maturation. The protein is located predominantly in mitochondria, yet low amounts are present in cytosol and nucleus.

Two-step membrane binding by the bacterial SRP receptor enable efficient and accurate Co-translational protein targeting

open access: yeseLife, 2017
The signal recognition particle (SRP) delivers ~30% of the proteome to the eukaryotic endoplasmic reticulum, or the bacterial plasma membrane. The precise mechanism by which the bacterial SRP receptor, FtsY, interacts with and is regulated at the target ...

Revisiting protein aggregation as pathogenic in sporadic Parkinson and Alzheimer diseases. [PDF]

open access: yes, 2019
The gold standard for a definitive diagnosis of Parkinson disease (PD) is the pathologic finding of aggregated α-synuclein into Lewy bodies and for Alzheimer disease (AD) aggregated amyloid into plaques and hyperphosphorylated tau into tangles.

Protein modification and degradation in ferroptosis

open access: yesRedox Biology
Ferroptosis is a form of iron-related oxidative cell death governed by an integrated redox system, encompassing pro-oxidative proteins and antioxidative proteins.

Protein-protein interaction network and subcellular localization of the Arabidopsis thaliana ESCRT machinery

open access: yesFrontiers in Plant Science, 2011
The Endosomal Sorting Complex Required for Transport (ESCRT) consists of several multi-protein subcomplexes which assemble sequentially at the endosomal surface and function in multivesicular body (MVB) biogenesis.

Protein trafficking in the mitochondrial intermembrane space: mechanisms and links to human disease [PDF]

open access: yes, 2017
Mitochondria fulfill a diverse range of functions in cells including oxygen metabolism, homeostasis of inorganic ions and execution of apoptosis. Biogenesis of mitochondria relies on protein import pathways that are ensured by dedicated multiprotein ...

Protein Localization at Mitochondria-ER Contact Sites in Basal and Stress Conditions

open access: yesFrontiers in Cell and Developmental Biology, 2017
Mitochondria-endoplasmic reticulum (ER) contacts (MERCs) are sites at which the outer mitochondria membrane and the Endoplasmic Reticulum surface run in parallel at a constant distance.

Solution structure of a bacterial microcompartment targeting peptide and its application in the construction of an ethanol bioreactor [PDF]

open access: yes, 2014
Targeting of proteins to bacterial microcompartments (BMCs) is mediated by an 18-amino-acid peptide sequence. Herein, we report the solution structure of the N-terminal targeting peptide (P18) of PduP, the aldehyde dehydrogenase associated with the 1,2 ...
