Welcome to the CATPA Portal

This portal provides a library of family curations together with an available application the Curation and Alignment Tool for Protein Analysis (CATPA) that allows for the management and visualization of curation and annotation data at the residue level including deletions and motifs as well. CATPA

• recognizes a number of well-known and widely used formats for importing to the system
• uses GO vocabulary
• runs stand-alone on most platforms
• is customizable with color choice for affinities

A quick overview of CATPA will be presented here. CATPA utilizes a Java GUI front-end that allows biologists to interact with information in an environment they are accustomed to. Protein families are aligned, and conservation and curation are easily discernable via colors that users can change according to their preferences. Additionally, in future implementations, other kinds of information can be displayed, e.g., entropy, hydrophobicity.

We have created a means of submitting web-viewable curations that can be found in the library. This way, researchers can view curations without having to download the application.

CATPA allows curations of text, URLs, and images. Its unique visualization system allows simultaneous zoom out and in, so that patterns as well as individual residues can be viewed.

A CATPA file can be shared so that multiple users can provide curation information.
