Coherent X-rays reveal anomalous molecular diffusion and cage effects in crowded protein solutions [PDF]

Nature Communications
Understanding protein motion within the cell is crucial for predicting reaction rates and macromolecular transport in the cytoplasm. A key question is how crowded environments affect protein dynamics through hydrodynamic and direct interactions at ...

Recognition of DNA damage by XPC coincides with disruption of the XPC–RAD23 complex [PDF]

Journal of Cell Biology, 2012
The recognition of helix-distorting deoxyribonucleic acid (DNA) lesions by the global genome nucleotide excision repair subpathway is performed by the XPC–RAD23–CEN2 complex. Although it has been established that Rad23 homologs are essential to protect XPC from proteasomal degradation, it is unclear whether RAD23 proteins have a direct role in the ...

Sequence of the mouse XPC cDNA and genomic structure of the human XPC gene [PDF]

Nucleic Acids Research, 1996
The full length-mouse XPC cDNA contains a 2703 bp orf which encodes a polypeptide containing 900 amino acids. Overall, there is 75% identity in nucleotide sequence and 73% identity in amino acid sequence between mouse and human genes. The C-terminal half is more conserved (80%) than the N-terminal half (65%).
