AtTFDB is a comprehensive and public Arabidopsis transcription factor database. From this page, users may search the database for transcription factors in two ways:

a) By utilizing a specific LocusID or gene name search: The user may enter a LocusID such as At3g24650, or a text field (such as NAC). The results are listed in a Search Results table. If the user marks the box in the first column and then moves to the bottom of the list, either the nucleotide or protein sequence can be retrieved. The family name, gene name, and description are displayed. In addition, there are four Arabidopsis resources the user may use to retrieve additional information, (M) for MIPS (Munich Institute for Protein Sequences): the MATDB within the MIPS website contains all Arabidopsis sequences and annotation produced by the Arabidopsis Genome Initiative plus mitochondrial and chloroplast genomes. Sequences were consolidated from European sequencing projects, Cold Spring Harbor Lab, and Washington University. (T) for TIGR (The Institute for Genomic Research): An alternative DB of Arabidopsis sequences and annotations from all AGI labs. (S) for SALK: Utilizing the SIGnAL Arabidopsis Gene Mapping Tool, it provides a map of the genome area in which the locus is found. One the map, cDNA(full-length cloned copies of mRNA) and T-DNA(sites of insertion of Agrobacterium T-DNA in the Arabidopsis genome) information is displayed in relation to the LocusID entered. (A) for TAIR (The Arabidopsis Information Resource): A genomic data resource, collected from a wide variety of sources, with information about genes, markers, polymorphisms, maps, sequences, clones, DNA and seed stocks, gene families and proteins.

b) Browse Families: There are 41 families(includes one family under orphan category) of transcription factors currently listed. The user may click on a link to one of the families and see the same Search Results table as the Specific Search containing all transcription factors from the specific family.
