About FARSB

Cytogenetic location: 2q36.1 Genomic coordinates (GRCh38): 2:222,566,899-222,656,092 (from NCBI)

This gene has 2 transcripts (splice variants), 212 orthologues, 1 paralogue and is associated with 2 phenotypes. Ubiquitous expression in brain (RPKM 8.3), testis (RPKM 8.2) and 25 other tissues.

Summary

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. [provided by RefSeq, Jan 2015]
