| abstractText | ADP-ribosylation factors (ARFs) and ARF-like proteins (ARLs) are part of the ARF family within the RAS superfamily of regulatory GTPases. Guanine nucleotide binding proteins or GTPases are involved in a diverse spectrum of cellular activities, including regulating cell growth and signal transduction, organization of the cytoskeleton and regulating membrane trafficking along the exocytic and endocytic pathways. ARL proteins share 40-60% sequence identity with the ARF proteins, but ARLs can be distinguished from ARFs based on expression patterns and biological functions. We have identified a new ARL, ARL8, from a fetal cartilage cDNA library. ARL8 contains six exons and five introns, and encodes a 179 amino acid protein that shares homology to the other ARL proteins, especially ARL5. It also shows significant homology with orthologous proteins found in Mus musculus and Drosophila melanogaster. The expression pattern of the mouse ortholog revealed differential tissue expression and an alternate transcript was seen in brain that was age-dependent. ARL8 is an additional member of a family of closely related proteins that are conserved both within the family and across species. |
