Crystal Structure of the Sixth BRCT Domain of Human TopBP1

Structural highlights

3pd7 is a 2 chain structure with sequence from Homo sapiens. This structure supersedes the now removed PDB entry 3l3e. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:	X-ray diffraction, Resolution 1.26Å
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

TOPB1_HUMAN Required for DNA replication. Plays a role in the rescue of stalled replication forks and checkpoint control. Binds double-stranded DNA breaks and nicks as well as single-stranded DNA. Recruits the SWI/SNF chromatin remodeling complex to E2F1-responsive promoters. Down-regulates E2F1 activity and inhibits E2F1-dependent apoptosis during G1/S transition and after DNA damage. Induces a large increase in the kinase activity of ATR.^[1] ^[2] ^[3] ^[4] ^[5] ^[6]
