genBlastG: using BLAST searches to build homologous gene models

Rong She, Jeffrey Shih-Chieh Chu, Bora Uyar, Jun Wang, Ke Wang, Nansheng Chen
2011 Computer applications in the biosciences : CABIOS  
Results: Here we report an efficient algorithm, genBlastG that directly uses the HSPs reported by BLAST to define high-quality gene models.  ...  Motivation: BLAST users frequently expect to obtain homologous genes with certain similarity to their query genes.  ...  These issues are not considered in genBlastA. genBlastG builds gene models by maximizing the similarity to their corresponding queries.  ...

We also review our approaches to sequence curation, and discuss the impact on annotation quality of large functional genomics projects such as modENCODE.  ...  Gene predictions by genBlastG 49 based on BLAST homologies to C. elegans proteins have also proved valuable for the curation of C. briggsae, C. brenneri, and C. remenei.  ...  These can be used both to confirm introns already part of curated gene models, and also to suggest changes to existing gene models or new isoforms.  ...
