**Background of Recombinant Human GNAL Protein**
The GNAL gene encodes the guanine nucleotide-binding protein Gα(olf) subunit, a member of the G-protein alpha subunit family involved in intracellular signaling. Gα(olf) is predominantly expressed in the brain, particularly in the striatum, olfactory bulb, and pituitary gland, where it couples with G-protein-coupled receptors (GPCRs) like dopamine D1 and adenosine A2A receptors to modulate cyclic adenosine monophosphate (cAMP) signaling. This pathway is critical for neurotransmission, olfactory sensing, and hormonal regulation.
GNAL mutations have been linked to neurological disorders, including Parkinson’s disease and bipolar disorder, highlighting its role in neuronal function. Recombinant human GNAL protein is produced via heterologous expression systems (e.g., E. coli or mammalian cells) for functional studies. Its purification often involves affinity tagging (e.g., His-tag) and validated activity assays (e.g., GTPase or cAMP response). Researchers utilize recombinant GNAL to explore GPCR signaling mechanisms, dissect disease-related mutations, and screen therapeutic agents targeting cAMP-associated pathways. Structural studies of Gα(olf) also aid in understanding its interaction with receptors and effectors, providing insights into cell signaling dysregulation in pathologies.
