This crystal structure was determined using X-ray diffraction at a resolution of 1.45 Å and deposited in 2008.

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

The PDB entry contains the structure of Intersectin-1. This molecule has the UniProt identifier Q15811 (ITSN1_HUMAN)search. The sample contained 121 residues which is < 90% of the natural sequence. Out of 121 residues 97 were observed and are deposited in the PDB.

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule is most likely monomeric.
