UniBind List Tfs

List the catalog of transcription factors (TFs) profiled in the UniBind database of direct TF-DNA binding sites. Optionally filter by a case-insensitive substring of the TF gene symbol via 'search' (e.g. 'SMAD' returns SMAD2, SMAD3, SMAD4...). Returns a sorted, de-duplicated list of TF gene symbols. Use this to discover valid tf_name values for UniBind_search_datasets. Public, no API key.
