Product Background

Gene summary
FARSB (Phenylalanyl-TRNA Synthetase Beta Subunit) is a Protein Coding gene. Among its related pathways are Gene Expression and tRNA Aminoacylation. GO annotations related to this gene include RNA binding and magnesium ion binding. An important paralog of this gene is LRRC47. This gene encodes a highly conserved enzyme that belongs to the aminoacyl-tRNA synthetase class IIc subfamily. This enzyme comprises the regulatory beta subunits that form a tetramer with two catalytic alpha subunits. In the presence of ATP, this tetramer is responsible for attaching L-phenylalanine to the terminal adenosine of the appropriate tRNA. A pseudogene located on chromosome 10 has been identified. Alternative splicing results in multiple transcript variants.
