Abstract:
Immunoreactivity of GABA(A) receptor subunits and the receptor anchoring protein gephyrin was investigated in the human globus pallidus using antibodies raised against the alpha(1) and gamma(2) subunits of the GABA(A) receptor complex and gephyrin. The results revealed increased GABA(A) receptor subunit immunoreactivity and unchanged levels of gephyrin immunoreactivity in Huntington's diseased (HD) globus pallidus (GP). The results demonstrate that gephyrin immunoreactivity did not change in unison with GABA(A) receptor changes in HD, suggesting that the receptor anchoring protein gephyrin is unaltered and maintains a stable lattice structure in the face of GABA(A) receptor changes in HD.

G Protein-coupled Receptors
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...
Rab Proteins
Rab proteins switch between a cytosolic, GDP-bound inactive state and a membrane-anchored, GTP-bound active state. By themselves, Rabs show slow rates of GDP/GTP exchange and GTP hydrolysis. Thus, Rab proteins are considered...
