IFITM3蛋白產品信息

別名: IFITM3
表達方式: A DNA sequence encoding the human IFITM3(NP_066362.2) (Met1-His57) was expressed, fused with the Fc region of mouse IgG1 at the N-terminus.
種屬: Human
表達宿主: Human Cells

IFITM3 Protein QC Testing

純度: > 99 % as determined by SDS-PAGE SDS-PAGE
內**: < 1.0 EU per μg of the protein as determined by the LAL method
穩定性: Samples are stable for up to twelve months from date of receipt at -70℃
預測N端: Asp
分子量: The recombinant human IFITM3/Fc is a disulfide-linked homodimer. The reduced monomer comprises 293 amino acids and has a predicted molecular mass of 32.9 kDa. The apparent molecular mass of the monomer is approximately 33-45 kDa in SDS-PAGE under reducing conditions due to glycosylation.
緩沖液: Lyophilized from sterile PBS,pH7.4.
Normally 5 % - 8 % trehalose and mannitol are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA.
Please contact us for any concerns or special requirements.

IFITM3 Protein Usage Guide

儲存方法: Store it under sterile conditions at -70℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution: A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.

IFITM3蛋白背景綜述

Interferon-induced transmembrane protein 3 (IFITM3) belongs to the CD225 family. It is an IFN-induced antiviral protein that mediates cellular innate immunity to at least three major human pathogens, namely influenza A H1N1 virus, West Nile virus (WNV), and dengue virus (WNV), by inhibiting the early step(s) of replication. IFITM3 is both necessary and sufficient for preventing the emergence of viral genomes from the endosomal pathway. To replicate, viruses must gain access to the host cell's resources. Interferon (IFN) regulates the actions of a large complement of interferon effector genes (IEGs) that prevent viral replication. The interferon inducible transmembrane protein family members, IFITM1, 2 and 3, are IEGs required for inhibition of influenza A virus, dengue virus, and West Nile virus replication in vitro. Notably, viral pseudoparticles were inhibited from transferring their contents into the host cell cytosol by IFN, and IFITM3 was required and sufficient for this action. IFITM3 overexpression is sufficient for this phenotype. Moreover, IFITM3 partially resides in late endosomal and lysosomal structures, placing it in the path of invading viruses.
