Function
function
Binds to a number of sites in the transcriptional regulatory region of ftz (PubMed:2104801).
Isoform beta is required to repress inappropriate segmentation gene transcription and repress genes incompatible with development of photoreceptor cell fates (PubMed:12384587, PubMed:18160715).
Probable repressor of the transcription of the segmentation genes ftz, eve, h, odd, run, and en (PubMed:8223261).
Inhibits Trl-dependent activation of eve (PubMed:12384587).
May bind to the region AGGGC/TGG (PubMed:8247159).
Degradation of ttk is directed by binding of sinah or sina, via the adapter molecule phyl which binds to the BTB domain of ttk (PubMed:17962185, PubMed:18160715).
A second method of degradation exists that is phyl-independent, this is mediated by recognition of motifs in the C-terminus of ttk (PubMed:17962185).

Post-translational modification
Polyubiquitinated by sina. Polyubiquitin linkage is mainly through 'Lys-48', but linkage through 'Lys-63' also occurs. Deubiquitination by Usp47 leads to its stabilization.
