malfunction

when arginine is administered 2 h prior to brain dissection, the KTP levels in these regions plus olfactory bulb significantly increase, although basal brain KTP levels remain relatively even

Mus musculus

malfunction

TyrRS knockdown of PC12 cells with a small interfering RNA (siRNA) in the presence of 1.6mM tyrosine, arginine, proline, or tryptophan significantly reduces the level of KTP, but not those of tyrosine-tyrosine, tyrosine-proline, or tyrosine-tryptophan. siRNA treatment does not affect cell survival or proliferation

Rattus norvegicus

physiological function

tyrosyl-tRNA synthetase is a potential kyotorphin synthetase (i.e. tyrosine-arginine ligase, EC 6.3.2.24) in mammals, positive correlation across brain regions between TyrRS expression and arginine-accelerated KTP production; TyrRS knockdown of PC12 cells with siRNA in the presence of 1.6 mM tyrosine, arginine, proline, or tryptophan significantly reduces the level of product kyotorphin, but not those of tyrosine-tyrosine, tyrosine-proline, or tyrosine-tryptophan. siRNA treatment does not affect cell survival or proliferation
