The service provides access to a database of factor-binding profiles depicting genetic makeups and structures typical of species. It provides biological researchers with lookup access to matrices defining genetic relationships documented through research. API methods generate profiles of transcription factor binding sites in varying formats, including Position Frequency Matrices (PFM), Position Weight Matrices (PWM), and Information Content Matrices (ICM). Methods support retrieval of all matrices or of a specific matrix specified by system ID or name. The API also supports search among matrices described in the system by topic-specific tags applied.
