If you are looking for Cn3D, you have come to the right place. We explain what Cn3D is and point you to the official download.

What is Cn3D?

The Cn3D software is a visualization program for biomolecular structures, sequences, and sequence alignments. The program is normally run as a helper application for web browsers to help you view 3-dimensional structures from NCBI's Entrez, but it can also be used as a standalone application. It is available for Windows, Macintosh, and different UNIX platforms. It has been used as the primary alignment curation tool for the CDD project.

Cn3D can display structure-structure alignments along with their structure-based sequence alignments, to emphasize what regions of a group of related proteins are most conserved in structure and sequence. In addition, it also includes custom labeling features, high-quality OpenGL graphics, and a wide range of file exports. Furthermore, it also serves as a complete multiple alignment editor with the integration of algorithms for aligning sequences to other sequences and to structures. The program can read structures which originate from MMDB, the Molecular Modeling Database at NCBI, which is a validated subset of the Protein Data Bank.
