    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.

    Lyophilized powder
    Note: We will preferentially ship the format that we have in stock, however, if you have any special requirement for the format, please remark your requirement when placing the order, we will prepare according to your demand.
  • 复溶：
    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.
  • 储存条件：
    Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw cycles.

  • 功能：
    Stimulates retinal guanylyl cyclase when free calcium ions concentration is low and inhibits guanylyl cyclase when free calcium ions concentration is elevated. This Ca(2+)-sensitive regulation of retinal guanylyl cyclase is a key event in recovery of the dark state of rod photoreceptors following light exposure. May be involved in cone photoreceptor light response and recovery of response in bright light.

    10. RetGC1 activation by GCAP1 involves establishing a tight complex through the binding patch with an additional activation step involving Met-26, Lys-85, and Trp-94. PMID: 24567338
    11. All four mutant GCAP1 family members showed sensitivity or acuity losses relative to normal observers. PMID: 24557353
    12. we predicted that either haploinsufficiency or dominant-negative effect accompanied by creation of a novel function for the mutant protein is a possible mechanism of the retinal degeneration due to c.250C>T and c.320T>C of the GUCA1A PMID: 24024198

    17. role in rescuing cone recovery kinetics in knockout mice PMID: 12732716
    18. The dynamic range for recombinant photoreceptor guanylyl cyclase-1 regulation by calcium (Ca2+)/GCAP1 is determined by both the affinity of GCAP1 for Ca2+ and relative affinities of the effector enzyme for the Ca2+-free versus Ca2+-loaded GCAP1. PMID: 15504042
    19. A novel GCAP1 mutation, I143NT, caused a form of autosomal dominant cone degeneration that destroys foveal cones by mid-life but spares some cones in the peripheral retina up to 75 years. PMID: 15505030

    22. This is the first report of this mutation also causing both cone-rod dystrophy and isolated macular dysfunction. PMID: 15953638
    23. metal binding in EF-hand 2 is crucial for GCAP1 attachment to RetGC1, and in EF-hand 3 it is less critical, although it enhances the efficiency of the GCAP1 docking on the target enzyme PMID: 18541533
