Coevolution-based inference of amino acid interactions underlying protein function

eLife, 2018
Protein function arises from a poorly understood pattern of energetic interactions between amino acid residues. Sequence-based strategies for deducing this pattern have been proposed, but lack of benchmark data has limited experimental verification. Here,

β‐TrCP overexpression enhances cisplatin sensitivity by depleting BRCA1

Molecular Oncology, EarlyView.
Low levels of β‐TrCP (Panel A) allow the accumulation of BRCA1 and CtIP, which facilitate the repair of cisplatin‐induced DNA damage via homologous recombination (HR) and promote tumor cell survival. In contrast, high β‐TrCP expression (Panel B) leads to BRCA1 and CtIP degradation, impairing HR repair, resulting in persistent DNA damage and apoptosis ...

Targeting of the hepatitis B virus precore protein to the endoplasmic reticulum membrane: after signal peptide cleavage translocation can be aborted and the product released into the cytoplasm. [PDF]

, 1988
The major hepatitis B virus (HBV) core protein is a viral structural protein involved in nucleic acid binding. Its coding sequence contains an extension of 29 codons (the "precore" region) at the amino terminus of the protein which is present in a ...

Targeting of PTP4A3 overexpression sensitises HGSOC cells towards chemotherapeutic drugs

Molecular Oncology, EarlyView.
In HGSOC with normal KRAS expression, high PTP4A3 expression regulates autophagy activation. Conversely, in HGSOC with high KRAS expression, KRAS dictates autophagy control, and PTP4A3 is not required. When high PTP4A3 expression is inhibited, HGSOC cells are preferentially sensitised towards DNA‐damaging agents.

Variation in HIV-1 Tat and Vpr protein amino acid sequences and its association with vascular health measures in a South African cohort: an exploratory study

Virology Journal
Objectives Human immunodeficiency virus (HIV)-1 is associated with adverse cardiovascular-related outcomes. Subtype-specific variations in the amino acid sequences of Tat and Vpr HIV-1 proteins are associated with differential clinical outcomes in people

Cloning of NruI and Sbo13I restriction and modification sstems in E. coli and amino acid sequence comparison of M.NruI and M.Sbo13I with other amino-methyltransferases

BMC Research Notes, 2010
Background NruI and Sbo13I are restriction enzyme isoschizomers with the same recognition sequence 5' TCG↓CGA 3' (cleavage as indicated↓). Here we report the cloning of NruI and Sbo13I restriction-modification (R-M) systems in E. coli.

Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids

Molecular Oncology, EarlyView.
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.
