Glutaurine is formed from the amino group of taurine with the gamma-carboxy group of L-glutamic acid. It was originally discovered in the parathyroid. Evidence has been found suggesting that glutaurine plays a role in peripheral thyroid hormonal regulation. Glutaurine increases triiodothyronine (T3) levels, but does not alter thyroxine (T4) levels. Glutaurine was also shown to prevent electroconvulsive shock-induced amnesia by counteracting the shock effect on the memory consolidation phase. Other roles that have been suggested for glutaurine include roles as a mouse metabolite, a mammalian metabolite, a human metabolite, an anticonvulsant, an anxiolytic drug and a hormone.
