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.

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.

Target Background

Function
(From Uniprot)
Catalytic subunit of the gamma-secretase complex, an endoprotease complex that catalyzes the intramembrane cleavage of integral membrane proteins such as Notch receptors and APP (amyloid-beta precursor protein). Requires the presence of the other members of the gamma-secretase complex for protease activity. Plays a role in Notch and Wnt signaling cascades and regulation of downstream processes via its role in processing key regulatory proteins.
Subcellular Location Endoplasmic reticulum membrane, Multi-pass membrane protein, Golgi apparatus membrane, Multi-pass membrane protein, Cytoplasmic granule, Cell membrane, Cell projection, axon, Cell junction, synapse
Protein Families Peptidase A22A family
Tissue Specificity Highest expression in ovaries and to a lesser extent in testis, intestine, kidney, brain, eye and lung. Weak expression in liver and heart. Present in trace amounts in skeletal muscle.
