Recombinant Human AIMP1 / EMAP2 / SCYE1 Protein, His tag, 100µg

Background
Aminoacyl tRNA synthase complex-interacting multifunctional protein 1 (AIMP1) is also known as multisynthase complex auxiliary component p43 and endothelial monocyte-activating polypeptide II (EMAP-II). AIMP1 is a cytokine that may be induced by apoptosis and is also released from professional antigen-presenting cells such as dendritic cells. The release of AIMP1 renders the tumor-associated vasculature sensitive to tumor necrosis factor. Furthermore, AIMP1 binds tRNA and stimulates the catalytic activity of cytoplasmic arginyl-tRNA synthase. This protein possesses inflammatory cytokine activity. Also, AIMP1 negatively regulates TGF-beta signaling through stabilization of SMURF2 by binding to SMURF2 and inhibiting its SMAD7-mediated degradation.

Source
Recombinant Human AIMP1, His Tag (EM2-H5142) is expressed from E.coli cells. It contains AA Ala 2 - Lys 312 (Accession # Q12904-1).
Predicted N-terminus: Met

Molecular Characterization
This protein carries a polyhistidine tag at the N-terminus.
The protein has a calculated MW of 35.2 kDa. The protein migrates as 36 kDa under reducing (R) condition (SDS-PAGE).

Endotoxin
Less than 1.0 EU per μg by the LAL method.

Purity
>95% as determined by SDS-PAGE.

Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally Trehalose are added as protectants before lyophilization.

Reconstitution
See Certificate of Analysis for reconstitution instructions and specific concentrations.

Storage
