We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

XP-A is a rare human autosomal recessive disease characterized by solar sensitivity, high predisposition for developing cancers on areas exposed to sunlight and, in some cases, neurological abnormalities. Group A patients show the most severe skin symptoms and progressive neurological disorders.<ref>PMID:1339397</ref> <ref>PMID:1372103</ref> <ref>PMID:9671271</ref> | ||

| + | The solution structure of the central domain of the human nucleotide excision repair protein XPA, which binds to damaged DNA and replication protein A (RPA), was determined by nuclear magnetic resonance (NMR) spectroscopy. The central domain consists of a zinc-containing subdomain and a C-terminal subdomain. The zinc-containing subdomain has a compact globular structure and is distinct from the zinc-fingers found in transcription factors. The C-terminal subdomain folds into a novel alpha/beta structure with a positively charged superficial cleft. From the NMR spectra of the complexes, DNA and RPA binding surfaces are suggested. | ||
