SCYE1
| View/Edit Human | View/Edit Mouse |
Aminoacyl tRNA synthetase complex-interacting multifunctional protein 1 is a protein that in humans is encoded by the AIMP1 gene.[3][4][5]
The protein encoded by this gene 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 this cytokine renders the tumor-associated vasculature sensitive to tumor necrosis factor. The precursor of SCYE1 (pro-SCYE1) is identical to the p43 subunit, which is associated with the multiaminoacyl-tRNA synthetase complex (mARS). Pro-SCYE1 may function in binding RNA as part of the tRNA synthetase complex in normal cells and in stimulating inflammatory responses after proteolytic cleavage in tumor cells.[5] As an inflammatory cytokine, AIMp1/p43 has demonstrated the ability to skew T-helper polarization in the direction of Th-1, and its homozygous deletion leads to a hyper-polarized Th-2 phenotype.
Interactions
SCYE1 has been shown to interact with SMURF2.[6]
