How to Use IIDB
Gene Maps
All data search functions are implemented for gene maps derived from the NCBI mouse gene build (version 33) and also the Ensembl mouse gene build (version 29e). You can specify which map to use.
The NCBI gene map is the default.

TF site at -440 in gene C will not be reported since it lies beyond the 100 nucleotide window of any of TF sites reported in gene A or B.
