An ultraviolet-driven rescue pathway for oxidative stress to eye lens protein human gamma-D crystallin.

Human gamma-D crystallin (HGD) is a major constituent of the eye lens. Aggregation of HGD contributes to cataract formation, the leading cause of blindness worldwide. It is unique in its longevity, maintaining its folded and soluble state for 50-60 years.

A Simple, Robust, and Cost-effective Method for Genotyping Small-scale Mutations.

Background And Objectives: Genotyping is an important tool for studying gene functions in animals or detecting genetic variants in humans. Various methods using low to high concentrations of agarose or polyacrylamide gel electrophoresis have been developed for genotyping. These methods rely on the detection of large-size differences (20-2,000 bp) of targeted PCR products between a wild-type gene and a mutant gene.

USP5 enhances SGTA mediated protein quality control.

Mislocalised membrane proteins (MLPs) present a risk to the cell due to exposed hydrophobic amino acids which cause MLPs to aggregate. Previous studies identified SGTA as a key component of the machinery that regulates the quality control of MLPs. Overexpression of SGTA promotes deubiqutination of MLPs resulting in their accumulation in cytosolic inclusions, suggesting SGTA acts in collaboration with deubiquitinating enzymes (DUBs) to exert these effects.
