**Background of RASD2 Recombinant Protein**
RASD2 (RASD family member 2), also known as Rhes, is a small monomeric GTPase belonging to the Ras superfamily of GTP-binding proteins. It was initially identified as a dexamethasone-induced gene in pituitary cells and is highly expressed in the striatum, a brain region critical for motor control and reward-related behaviors. Structurally, RASD2 shares homology with other Ras proteins but exhibits unique functional properties, including the ability to interact with mTOR (mechanistic target of rapamycin) pathways and modulate dopamine receptor signaling.
RASD2 plays a multifaceted role in cellular processes such as vesicular trafficking, neurotransmitter regulation, and cell survival. Notably, it has been implicated in neurological and psychiatric disorders. Studies link RASD2 dysfunction to Huntington’s disease, Parkinson’s disease, and schizophrenia, partly due to its interaction with mutant huntingtin protein and its influence on dopaminergic transmission. Its dual role as a GTPase and a scaffolding protein enables it to regulate signal transduction cascades, making it a potential therapeutic target.
Recombinant RASD2 protein is engineered using expression systems (e.g., *E. coli* or mammalian cells*) to produce purified, bioactive forms for research. This tool enables *in vitro* studies of its enzymatic activity, protein interactions, and structural properties. Researchers utilize it to explore RASD2’s role in disease mechanisms, screen drug candidates, or validate binding partners via assays like pull-downs or surface plasmon resonance (SPR).
Overall, RASD2 recombinant protein serves as a vital resource for deciphering the molecular basis of neuropathologies and advancing targeted therapies. Its study bridges gaps between cellular signaling, brain function, and disease, highlighting its significance in both basic and translational neuroscience.
