Functioni

Orphan receptor that binds DNA as a monomer to hormone response elements (HRE) containing an extended core motif half-site sequence 5'-AAGTCA-3' in which the 5' flanking nucleotides participate in determining receptor specificity. This receptor binds to the consensus sequence [AG][AG]AAGTCAA. Plays a key role in the establishment of non-metameric domains at the anterior and posterior poles of the embryo. It may also play a role in the nervous system. The maternal terminal pathway activates the tll gene in the termini; TLL activity then represses segmentation and activates terminal-specific genes in these domains. Involved in the regulation of early eye development. In the embryonic visual system anlage drives cells to optic lobe as opposed to Bolwig's organ fate.2 Publications

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
