They are extensively used at TAGC and elsewhere to select clones for use in research projects. Due to chimeres, sequencing errors, and alternative splicing, there is often more than one cluster per gene. Each UniGene cluster contains sequences that represent a unique gene, as well as related information such as the tissue types in which the gene has been expressed and map location. No attempt is made to produce contigs or consensus sequences. All of the splicing variants for a gene are put into the same set.
Indices exist for mouse rat and human .
Fingerprints can encode protein folds and functionalities more flexibly and powerfully than can single motifs. DOMO database of aligned domains constructed from a fully automated process utilizing only sequence information. Other Protein Families from UC San Diego. Protein family sites from ProWeb. Gene Family Database prototype database of gene families in the human and mouse that contains both community curated information and hypertext links to various biological databases.
