DNA binding domain: Difference between revisions

Revision as of 16:58, 1 December 2016

A DNA binding domain (DBD) is part of a protein with a high affinity for DNA. For example, transcription factors. DBDs have a minimum of one motif which can bind to non-sequence specific or sequence specific DNA. Structural motifs can interact with single stranded and double stranded DNA. The functions of DBDs include allowing structural changes to take place to a protein and to allow regulation of transcription.^[1]

Some common examples of DBDs include:
