Kinetic differences in GABA receptor binding following GABA and bicuculline methiodide pretreatment. 1984

G Maksay, and M K Ticku

The kinetics of [3H]GABA binding were studied in cortical membranes following GABA and bicuculline methiodide (BCM) pretreatment at 37 degrees C. The slower parts of the biphasic ON and OFF rates can be attributed to the high affinity sites. BCM pretreatment decreased the ON and OFF rates of [3H]GABA binding, including the rapid initial ON- and OFF-phases. Decreased association rates of GABA were independent of GABA and concentration and suggested a rate determining dissociation of bound BCM (t1/2 = 35 min).

UI	MeSH Term	Description	Entries
D007700	Kinetics	The rate dynamics in chemical or physical systems.
D011963	Receptors, GABA-A	Cell surface proteins which bind GAMMA-AMINOBUTYRIC ACID and contain an integral membrane chloride channel. Each receptor is assembled as a pentamer from a pool of at least 19 different possible subunits. The receptors belong to a superfamily that share a common CYSTEINE loop.
