Research Areas:Immunology
Uniprot ID:P68978
Gene Names:N/A
Organism:Human adenovirus C serotype 2 (HAdV-2) (Human adenovirus 2)
AA Sequence:AKKVEFKEPACNVTFKSEANECTTLIKCTTEHEKLIIRHKDKIGKYAVYAIWQPGDTNDYNVTVFQGENRKTFMYKFPFYEMCDITMYMSKQYKLWPPQKCLENTG
Expression Region:18-123aa
Sequence Info:Partial
Source:E.coli
Tag Info:N-terminal 10xHis-tagged and C-terminal Myc-tagged
MW:20.0 kDa
Alternative Name(s):E3-19K E3gp 19 kDa Short name: E19 GP19K
Relevance:Binds and retains class I heavy chains in the endoplasmic reticulum during the early period of virus infection, thereby impairing their transport to the cell surface. Also delays the expression of class I alleles that it cannot affect by direct retention. Binds transporters associated with antigen processing (TAP) and acts as a tapasin inhibitor, preventing class I/TAP association. In consequence, infected cells are masked for immune recognition by cytotoxic T-lymphocytes (By similarity).
Reference:"Conserved cysteine residues within the E3/19K protein of adenovirus type 2 are essential for binding to major histocompatibility complex antigens." Sester M., Burgert H.-G. J. Virol. 68:5423-5432(1994)
Purity:Greater than 90% as determined by SDS-PAGE.
Form:Liquid or Lyophilized powder
Buffer:If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol. If the delivery form is lyophilized powder, the buffer before lyophilization is 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: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?/-80?. The shelf life of lyophilized form is 12 months at -20?/-80?.
Notes:Repeated freezing and thawing is not recommended. Store working aliquots at 4? for up to one week.
