Nucleus.

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.

We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20 °C/-80 °C. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Delivery time may differ from different purchasing ways or locations, please kindly consult us for specific delivery times.

Store at -20 °C/-80 °C upon receipt, aliquoting is necessary for multiple use.

The shelf life is related to many factors, including storage state, buffer ingredients, storage temperature, and the stability of the protein itself. Generally, the shelf life of liquid form is 6 months at -20 °C/-80 °C. The shelf life of lyophilized form is 12 months at -20 °C/-80 °C.

Repeated freezing and thawing are not recommended.

This product is for research use only and is not approved for use in humans or in clinical diagnosis. Store working aliquots at 4 °C for up to one week.
