TBX

TBX
PFAM accession number:PF12598
Interpro abstract (IPR022582):

This eukaryotic region of unknown function is typically between 77 and 89 amino acids in length. It is found C-terminal to the T-box DNA binding domain. This region contains two completely conserved residues (S and P) that may be functionally important. T-box genes are highly conserved and encode transcription factors that are involved in morphogenesis and organogenesis of both invertebrates and vertebrates [(PUBMED:8597636)],[(PUBMED:8530034)].

This is a PFAM domain. For full annotation and more information, please see the PFAM entry TBX
