Conjugate Avi-tag Biotinylated
E. coli biotin ligase (BirA) is highly specific in covalently attaching biotin to the 15 amino acid AviTag peptide. This recombinant protein was biotinylated in vivo by AviTag-BirA technology, which method is BriA catalyzes amide linkage between the biotin and the specific lysine of the AviTag.

Buffer before Lyophilization Tris/PBS-based buffer, 6% Trehalose, pH 8.0
Reconstitution 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℃/-80℃. Our default final concentration of glycerol is 50%. Customers could use it as reference.

Storage Condition Store at -20°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.
Shelf Life The shelf life is related to many factors, 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.
Lead Time Delivery time may differ from different purchasing way or location, please kindly consult your local distributors for specific delivery time.
Note: All of our proteins are default shipped with normal blue ice packs, if you request to ship with dry ice, please communicate with us in advance and extra fees will be charged.
Notes Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.

Target Data

Function Homeotic protein that acts downstream of Arm in the Wg cascade during embryogenesis to determine segment identity throughout the entire trunk. Acts cooperatively with other trunk homeotic proteins to repress head homeotic genes and therefore repress head segmental identity. Necessary, in combination with Scr, for the formation of the prothoracic segment. Promotes eye development in the dorsal region of the eye disk and suppresses eye development in the ventral region in combination with Wg-signaling and several early dorso-ventral eye patterning genes. Required for proper development of proximal leg segments. Has differential functions along the dorso-ventral axs of the antennal and leg disks. May play a role in wing hinge development. Possible involvement in chromatin structure for modulation of transcription. Binds DNA and can act as both a transcriptional repressor and activator. Positively regulates its own expression as well as that of Dll. Negatively regulates the expression of mod. Required for Wg-mediated transcriptional repression of Ubx in the midgut. Also represses transcription of lab in the midgut and is necessary for the proper formation of anterior and central midgut structures. Tiptop (tio) and teashirt (tsh) have, on the whole, common activities. Tio and tsh repress each other's expression and tsh has a crucial role for trunk patterning that is in part masked by ectopic expression of tiptop. Both genes share a common activity required for the activation of Ser and svb and the maintenance of en and wg.
Gene References into Functions
  1. Hth+Tsh-induced tissue overgrowth requires the BMP2 Dpp and the abnormal hyperactivation of its pathway. Rather than using autocrine Dpp expression, Hth+Tsh cells increase their avidity for Dpp, produced locally, by upregulating extracellular matrix components. PMID: 27502436
  2. studies demonstrate a novel neuroprotective function of tsh and its paralog tio in Abeta42 mediated neurodegeneration PMID: 24282556
  3. Tiptop/teashirt genes regulate cell differentiation and renal physiology in Drosophila. PMID: 23404107
  4. Tsh contains three zinc finger motifs the second zinc finger is essential to the proper functioning of the protein while the remaining zinc finger domains appear to contribute but are not absolutely required PMID: 22019301
  5. The aeroplane phenotype is produced by an I-element inserted into a tissue-specific teashirt enhancer motif. PMID: 11681617
  6. Repression of Teashirt marks the initiation of wing development PMID: 11973273
  7. Eye suppression, a novel function of this protein, requires Wingless signaling PMID: 12183379
  8. Combinatorial control of Drosophila eye development by eyeless, homothorax, and teashirt. PMID: 12231630
  9. three mouse Tsh genes are functionally equivalent to the Drosophila tsh gene when expressed in developing Drosophila embryos PMID: 14973285
  10. promotes eye development in dorsal and suppressing eye development in ventral by Wingless mediated Homothorax (HTH) induction PMID: 15110046
  11. Wingless and Decapentaplegic act independently as the primary signals for the repression of tsh and homothorax, respectively PMID: 15509768
  12. Teashirt has a crucial role for trunk patterning PMID: 15936749
  13. Induces eye specification, at least in part, by allowing the activation of eye specification genes by the wingless (wg) and decapentaplegic (dpp) signaling pathways. PMID: 16221726
  14. Data show that tio (tiptop) and tsh (teashirt) have coincident expression domains in the imaginal discs, the precursors of the adult body, and that both genes show similar functional properties when expressed ectopically. PMID: 19097089
  15. Data demonstrate that ectopic eye formation by teashirt and its paralog tiptop, a potential new eye specification gene, is restricted to the developing antennae. PMID: 19347955
