Summary: Enables scaffold protein binding activity. Predicted to be involved in several processes, including ERK1 and ERK2 cascade; diadenosine tetraphosphate biosynthetic process; and lysyl-tRNA aminoacylation. Predicted to act upstream of or within translation. Located in mitochondrion. Part of aminoacyl-tRNA synthetase multienzyme complex. Is expressed in several structures, including alimentary system; central nervous system; cranium; genitourinary system; and sensory organ.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
