Supplementary information

ARMET also known as Arp is a 19 kDa protein known for its role in cellular stress responses. It is alternatively named MANF (Mesencephalic Astrocyte-derived Neurotrophic Factor) in some studies. This protein is widely expressed including in the brain liver and pancreas reflecting its involvement across different cellular environments. ARMET/ARP interacts with the endoplasmic reticulum to address misfolded protein loads and support cell survival under stress.
Biological function summary

ARMET plays a significant role in maintaining cellular homeostasis especially under stress conditions. It does not form a larger complex but functions as a standalone factor that aids in the proper folding of proteins within the endoplasmic reticulum. Additionally ARMET has protective effects on dopaminergic neurons which are critical for neuromolecular processes. This protein has connections to cellular survival pathways acting as a neurotrophic factor to support neuron maintenance and health.

Pathways

ARMET is an important player in the unfolded protein response (UPR) and the neuroprotective pathways. In these pathways ARMET interacts with other proteins involved in protein folding and stress responses such as BiP/GRP78. These interactions help prevent apoptosis and promote cell survival by ensuring that cells can cope with endoplasmic reticulum stress. The ability of ARMET to enhance neuronal survival links it to pathways important for neuroprotection.

ARMET has been associated with neurodegenerative diseases such as Parkinson's disease and diabetes. In Parkinson's disease the survival-promoting effects of ARMET on dopaminergic neurons become vital potentially offering therapeutic targets. Connections between ARMET and diabetes surface through its regulation of beta-cell survival in the pancreas suggesting a role in maintaining insulin production and glucose homeostasis. In these diseases ARMET may interact with other proteins like proinsulin which holds significance for maintaining endocrine functions.

Target data

Selectively promotes the survival of dopaminergic neurons of the ventral mid-brain (PubMed : 12794311). Modulates GABAergic transmission to the dopaminergic neurons of the substantia nigra (By similarity). Enhances spontaneous, as well as evoked, GABAergic inhibitory postsynaptic currents in dopaminergic neurons (By similarity). Inhibits cell proliferation and endoplasmic reticulum (ER) stress-induced cell death (PubMed : 18561914, PubMed : 22637475, PubMed : 29497057). Retained in the ER/sarcoplasmic reticulum (SR) through association with the endoplasmic reticulum chaperone protein HSPA5 under normal conditions (PubMed : 22637475). Up-regulated and secreted by the ER/SR in response to ER stress and hypoxia (PubMed : 22637475). Following secretion by the ER/SR, directly binds to 3-O-sulfogalactosylceramide, a lipid sulfatide in the outer cell membrane of target cells (PubMed : 29497057). Sulfatide binding promotes its cellular uptake by endocytosis, and is required for its role in alleviating ER stress and cell toxicity under hypoxic and ER stress conditions (PubMed : 29497057).
