ADP ribosylation factor 1 (Arf1) was cloned and characterized from Exopalaemon carinicauda.
Hemocytes and gills had the abundant EcArf1 expression among all the examined tissues.
EcArf1 mRNA expression in hemocytes and hepatopancreas induced significantly upon Vibrio parahaemolyticus and WSSV challenge.
EcArf1 showed significant increase in hepatopancreas and gills after ammonia-N stress.
The results imply that EcArf1 may be involved in pathogens challenge and ammonia-N stress.
