Gene name:
Aimp1(Emap2;Scye1);
Protein name:
Aminoacyl tRNA synthase complex-interacting multifunctional protein 1;
Alternative:
Multisynthase complex auxiliary component p43;
Organism:
Mouse (Mus musculus).
General Annotation
Sub Unit:
Homodimer (By similarity). Component of the multisynthase complex which is comprised of a bifunctional glutamyl-prolyl-tRNA synthase, the monospecific isoleucyl, leucyl, glutaminyl, methionyl, lysyl, arginyl and aspartyl-tRNA synthases, and three auxiliary proteins, EEF1E1/p18, AIMP2/p38 and AIMP1/p43. Interacts (via N-terminus) with RARS (via N-terminus). Interacts (via C-terminus) with SMURF2. Interacts (via N-terminus) with HSP90B1/gp96 (via C-terminus). Interacts with PSMA7.
Function:
Non-catalytic component of the multisynthase complex. Stimulates the catalytic activity of cytoplasmic arginyl-tRNA synthase. Binds tRNA. Possesses inflammatory cytokine activity. Negatively regulates TGF-beta signaling through stabilization of SMURF2 by binding to SMURF2 and inhibiting its SMAD7-mediated degradation. Involved in glucose homeostasis through induction of glucagon secretion at low glucose levels. Promotes dermal fibroblast proliferation and wound repair. Regulates KDELR1-mediated retention of HSP90B1/gp96 in the endoplasmic reticulum. Plays a role in angiogenesis by inducing endothelial cell migration at low concentrations and endothelian cell apoptosis at high concentrations. Induces maturation of dendritic cells and monocyte cell adhesion. Modulates endothelial cell responses by degrading HIF-1A through interaction with PSMA7.

Enriched in secretory vesicles of pancreatic alpha cells and secreted from the pancreas in response to low glucose levels. Also secreted in response to hypoxia and both apoptotic and necrotic cell death.
