Solution structure of CAPPD*, an independently folded extracellular domain of human Amyloid-beta Precursor Protein

The structure was published by Dulubova, I., Ho, A., Huryeva, I., Sudhof, T.C., and Rizo, J., in 2004 in a paper entitled "Three-dimensional structure of an independently folded extracellular domain of human amyloid-beta precursor protein." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2004.

The experimental data on which the structure is based was also deposited.

The PDB entry contains the structure of Amyloid beta A4 protein. This molecule has the UniProt identifier P05067 (A4_HUMAN)search. The sample contained 110 residues which is < 90% of the natural sequence. Out of 110 residues 110 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
