FLASH GENE DNA RNA EXPRESSION PROTEIN DISORDER ANIMAL & CELL MODELS

PROTEIN

PHYSICAL PROPERTIES

STRUCTURE

motifs/domains	a catalytic domain which interacts with the amino acid acceptor-T psi C helix of the tRNA
	a second domain which interacts with the rest of the tRNA structure
	L aminoacyl-tRNA synthetase domain (residues 1–254),
	the tRNA recognition domain (residues 255–451),
	the editing domain (residues 468–757),
	C-terminal domain (residues 758–968)

mono polymer

monomer

HOMOLOGY

Homologene

FAMILY

class-II aminoacyl-tRNA synthetase family

CATEGORY

enzyme

SUBCELLULAR LOCALIZATION	plasma membrane
	intracellular
	intracellular,cytoplasm,cytosolic

basic FUNCTION	enzymes that interpret the RNA code and attach specific aminoacids to the tRNAs that contain the cognate trinucleotide anticodons
	target autoantibodies in immune polymyositis/dermatomyositis
	ligate amino acids to their cognate tRNAs (Sang Lee 2002)
	catalyzes synthesis of Ala-tRNA(Ala) and hydrolysis of mis-acylated Ser- and Gly-tRNA(Ala) at 2 different catalytic sites

CELLULAR PROCESS

nucleotide, transcription, initiation

INTERACTION

DNA

RNA

small molecule

protein	interaction network of aminoacyl-tRNA synthetases and subunits of elongation factor 1 complex, systematic interaction network probably to enhance the efficiency of in vivo protein synthesis (Sang Lee 2002)
	translation requires the specific attachment of AAs to AARS and the subsequent delivery of aminoacyl-tRNAs to the ribosome by elongation factor 1 alpha (EEF1A2)
