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.

Tag Info
Tag type will be determined during the manufacturing process.
The tag type will be determined during production process. If you have specified tag type, please tell us and we will develop the specified tag preferentially.
Form
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.
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.
Troubleshooting and FAQs
Storage Condition
Store at -20°C/-80°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 Background

Function
Serine/threonine kinase that phosphorylates baf-1, thus regulating the association of baf-1 with chromatin and nuclear membrane proteins during nuclear envelope formation. May act through the egl-17 signaling pathway. Essential in hermaphrodites for formation of the vulva, uterus, and uterine seam cells and for development and maintenance of the somatic gonad and thus the germ line. Acts to prevent cep-1 from triggering an inappropriate cell cycle arrest, thereby promoting germ cell proliferation. Regulates anchor cell polarity and the timing of anchor cell invasion through the basement membranes separating vulval and somatic gonadal cells during the L3 larval stage.
Gene References into Functions
  1. vrk-1 has a role in early uterine development in Caenorhabditis elegans PMID: 26827901
  2. By coordinating VRK-1- and PP2A-mediated signaling on BAF, Lem4 and LEM-4L (Y55F3BR.8) controls postmitotic nuclear envelope formation in a function conserved from worms to humans. PMID: 22770216
  3. Data show that expression of the fibroblast growth factor-like protein EGL-17 and its receptor EGL-15 is reduced in vrk-1 mutants, suggesting that VRK-1 might act at least partially through activation of FGF signaling. PMID: 19679119
Subcellular Location
Nucleus.
Protein Families
Protein kinase superfamily, CK1 Ser/Thr protein kinase family, VRK subfamily
Tissue Specificity
Present in germ cells at all stages of progression from the mitotic zone to mature oocytes, but not in maturing spermatids (at the protein level). Expressed in the ventral nerve cord and vulva cells.
