Foundational characteristics of cancer include proliferation, angiogenesis, migration, evasion of apoptosis, and cellular immortality. Find key markers for these cellular processes and antibodies to detect them.
The SUMOplot™ Analysis Program predicts and scores sumoylation sites in your protein. SUMOylation is a post-translational modification involved in various cellular processes, such as nuclear-cytosolic transport, transcriptional regulation, apoptosis, protein stability, response to stress, and progression through the cell cycle.
The Autophagy Receptor Motif Plotter predicts and scores autophagy receptor binding sites in your protein. Identifying proteins connected to this pathway is critical to understanding the role of autophagy in physiological as well as pathological processes such as development, differentiation, neurodegenerative diseases, stress, infection, and cancer.

| Function | Intracellular G-protein coupled receptor for trace amines, which recognizes endogenous amine-containing metabolites such as beta- phenylethylamine (beta-PEA), 3-iodothyronamine (T1AM), isoamylamine (IAA), cadaverine (CAD), cyclohexylamine (CHA), p-tyramine (p-TYR), trimethylamine (TMA), octopamine and tryptamine (PubMed:11459929, PubMed:11723224, PubMed:15718104, PubMed:31399635, PubMed:36100653, PubMed:37935376, PubMed:37935377, PubMed:37963465, PubMed:38168118). Also functions as a receptor for various drugs and psychoactive substances, such as amphetamine and methamphetamine (PubMed:31399635, PubMed:37935376, PubMed:37935377). Unresponsive to classical biogenic amines, such as epinephrine and histamine and only partially activated by dopamine and serotonin (PubMed:11459929, PubMed:11723224). Expressed in both the central and peripheral nervous system: TAAR1 activation regulates the activity of several neurotransmitter signaling pathways by (1) decreasing the basal firing rates of the neurons involved and by (2) lowering the sensitivity of receptors to neurotransmitters (PubMed:37935376, PubMed:37935377, PubMed:37963465, PubMed:38168118). Ligand binding causes a conformation change that triggers signaling via guanine nucleotide-binding proteins (G proteins) and modulates the activity of downstream effectors (PubMed:31399635, PubMed:37935376, PubMed:37963465). TAAR1 is coupled with different G(i)/G(o)-, G(s)- or G(q)/G(11) classes of G alpha proteins depending on the ligand (PubMed:31399635, PubMed:37935376, PubMed:37963465). CAD-binding is coupled to G(i)/G(o) G alpha proteins and mediates inhibition of adenylate cyclase activity (PubMed:37935376, PubMed:37963465). T1AM- or beta-PEA-binding is coupled to G(s) G alpha proteins and mediates activation of adenylate cyclase activity (PubMed:37935376, PubMed:37963465). CHA- or IAA-binding is coupled to G(q)/G(11) G alpha proteins and activates phospholipase C-beta, releasing diacylglycerol (DAG) and inositol 1,4,5-trisphosphate (IP3) second messengers (PubMed:37935376, PubMed:37963465). TMA-binding is coupled with all three G(i)/G(o)-, G(s)- or G(q)/G(11) G alpha protein subtypes (PubMed:37935376, PubMed:37963465). Amphetamine-binding is coupled with G(s)- or G(12)/G(13) G alpha protein subtypes (PubMed:31399635). |

Cell membrane; Multi-pass membrane protein Note=Localizes mainly intracellularly (PubMed:11723224, PubMed:31399635, PubMed:36100653). Partially colocalizes with the endoplasmic reticulum; also found at lower lever at the plasma membrane (PubMed:36100653). |

Background
Receptor for trace amines, including beta- phenylethylamine (b-PEA), p-tyramine (p-TYR), octopamine and tryptamine, with highest affinity for b-PEA and p-TYR. Unresponsive to classical biogenic amines, such as epinephrine and histamine and only partially activated by dopamine and serotonine. Trace amines are biogenic amines present in very low levels in mammalian tissues. Although some trace amines have clearly defined roles as neurotransmitters in invertebrates, the extent to which they function as true neurotransmitters in vertebrates has remained speculative. Trace amines are likely to be involved in a variety of physiological functions that have yet to be fully understood. The signal transduced by this receptor is mediated by the G(s)-class of G-proteins which activate adenylate cyclase.
