Nuclear factor I protein pre-N-terminus; The Nuclear factor I (NFI) family of site-specific DNA-binding proteins (also known as CTF or CAAT box transcription factor) functions both in viral DNA replication and in the regulation of gene expression in higher organizms. The N-terminal 200 residues contains the DNA-binding and dimerization domain, but also has an 8-47 residue highly conserved region 5' of this, whose function is not known. Deletion of the N-terminal 200 amino acids removes the DNA-binding activity, dimerization-ability and the stimulation of adenovirus DNA replication.

MH1 domain; The MH1 (MAD homology 1) domain is found at the amino terminus of MAD related proteins such as Smads. This domain is separated from the MH2 domain by a non-conserved linker region. The crystal structure of the MH1 domain shows that a highly conserved 11 residue beta hairpin is used to bind the DNA consensus sequence GNCN in the major groove, shown to be vital for the transcriptional activation of target genes. Not all examples of MH1 can bind to DNA however. Smad2 cannot bind DNA and has a large insertion within the hairpin that presumably abolishes DNA binding. A basic helix (H2) in MH1 with the nuclear localization signal KKLKK has been shown to be essential for Smad3 nuclear import. Smads also use the MH1 domain to interact with transcription factors such as Jun, TFE3, Sp1, and Runx.
