Other Information

**Key characteristics:** - KCNJ6 is a transmembrane protein with a predicted molecular weight of approximately 145 kDa. - It is expressed in a variety of cell types, including neurons, astrocytes, and endothelial cells. - KCNJ6 is a homo-tetrameric protein, meaning it consists of four identical subunits that are arranged in a tetrahedral shape. - It is a ligand for the G protein-coupled receptor Gab1. **Pathways and functions:** - KCNJ6 is involved in a variety of cellular processes, including: - Activation of gabab receptors, which are G protein-coupled receptors that are expressed in a variety of brain regions. - Activation of g protein-gated potassium channels, which are another type of potassium channel that is regulated by G proteins. - Inhibition of voltage-gated calcium channels, which are another type of ion channel that is involved in neuronal excitability. - Regulation of monoatomic ion transmembrane transport. **Clinical significance:** - Mutations in the KCNJ6 gene have been linked to a number of neurological and psychiatric disorders, including autism, schizophrenia, and epilepsy. - KCNJ6 is a potential therapeutic target for these disorders, as it could be used to block the activity of gabab receptors or g protein-gated potassium channels. **Additional notes:** - KCNJ6 is a relatively new gene, and there is still a lot that is unknown about its function. - It is a promising target for the development of new treatments for neurological and psychiatric disorders.
