THE CRYSTAL STRUCTURE OF A TWO ZINC-FINGER PEPTIDE REVEALS AN EXTENSION TO THE RULES FOR ZINC-FINGER/DNA RECOGNITION

Structural highlights
FunctionTTKB_DROME Binds to a number of sites in the transcriptional regulatory region of ftz. Isoform beta is required to repress inappropriate segmentation gene transcription and repress genes incompatible with development of photoreceptor cell fates. Probable repressor of the transcription of the segmentation genes ftz, eve, h, odd, run, and en. Inhibits Trl-dependent activation of eve. May bind to the region AGGGC/TGG. Degradation of ttk is directed by binding of sinah or sina, via the adapter molecule phyl which binds to the BTB domain of ttk. A second method of degradation exists that is phyl-independent, this is mediated by recognition of motifs in the C-terminus of ttk.[1] [2] [3] [4] [5] Evolutionary ConservationCheck, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. References
