Developmental expression of amphioxus GABAA receptor-associated protein-like 2 gene.

A full-length amphioxus gamma-aminobutyric acid type-A receptor-associated protein-like 2 ( GABARAPL2) cDNA was isolated. Its sequence and developmental expression are first described in this paper. The phylogenetic analysis shows that the amphioxus GABARAPL2 and GABARAPL2 in vertebrates are highly homologous. The results of in situ hybridization show that the amphioxus GABARAPL2 gene is expressed in the neural tube, neurenteric canal, notochord, muscle and developing alimentary canal.
