Aspartyl-tRNA synthetase, cytoplasmic is an enzyme that in humans is encoded by the DARS gene. ^{[5] [6]}

Aspartyl-tRNA synthetase (DARS) is part of a multienzyme complex of aminoacyl-tRNA synthetases. Aspartyl-tRNA synthetase charges its cognate tRNA with aspartate during protein biosynthesis. ^[6]

Clinical significance

Mutations in DARS have been identified as the cause of leukoencephalopathy, hypomyelination with brain stem and spinal cord involvement and leg spasticity (HBSL). ^[7]
