Crystal structure of Pot1 (protection of telomere)- ssDNA complexCrystal structure of Pot1 (protection of telomere)- ssDNA complex

Structural highlights

1qzh is a 12 chain structure with sequence from Schizosaccharomyces pombe. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.4Å
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

POT1_SCHPO Single-stranded telomeric DNA-binding protein that is required to protect the 3'-end telomeric overhang. It binds the consensus sequence 5'-GGTTAC-3'. Regulates telomerase and telomere length.[1] [2] [3]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
