Summary: Enables mRNA binding activity. Acts upstream of or within protein localization to axon and protein localization to cell leading edge. Located in COPI-coated vesicle; Golgi apparatus; and growth cone. Is expressed in several structures, including brain; jaw bone; and thoracic segment skeleton. Orthologous to human COPA (COPI coat complex subunit alpha). [provided by Alliance of Genome Resources, Apr 2022]

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.
