GO:0001030

Interacting selectively and non-covalently with a region of DNA that is a part of a type 1 promoter that controls transcription by RNA polymerase III. Type 1 promoters are found in 5S rRNA genes, downstream of the transcription start site within the sequence of the mature RNA, and require TFIIIA for recognition. [GOC:txnOH, PMID:12381659]
