Chaperoning the DNA damage response

Deciphering the DNA Damage Response

This year's Albert Lasker Basic Medical Research Award honors Evelyn Witkin and Stephen J. Elledge, two pioneers in elucidating the DNA damage response, whose contributions span more than 40 years.

DNA Damage Response Pathways

ownload B4 is unusual among receptor tyrosine kinases because some isoforms can be efficiently cleaved at the a membrane to release a soluble intracellular domain. The cleavage product has high kinase activity mes to the nucleus. A screen for proteins that associate with the ErbB4 intracellular domain identified ate interactors including ITCH, WWP2, Nucleolin, and Krab-associated protein 1 (Kap...

The Role of chk2 in Response to DNA Damage in Cancer Cells

Accumulation of gene changes and chromosomal instability in response to cellular DNA damage lead to cancer. DNA damage induces cell cycle checkpoints pathways. Checkpoints regulate DNA replication and cell cycle progression, chromatin restructuring, and apoptosis. Checkpoint kinase 2 (chk2) is activated in response to DNA lesions. ATM phosphorylate chk2. The activated Chk2 kinase can phosphoryl...

DNA damage response and neuroprotection.

The protection of genomic integrity is a major challenge for living cells that are continuously exposed to endogenous and environmental DNA-damaging insults. To cope with the consequences of DNA lesions which interfere with essential DNA-dependent processes including transcription and replication, cells are equipped with an efficient defense mechanism termed the DNA damage response. Its functio...
