چکیده انگلیسی
The transcription factor activator protein-1 (AP-1) is an important gene expression regulator with typical Jun and region-leucine zipper (bZIP) domains and can respond to a plethora of physiological and pathological stimulus. In this study, we identified a novel AP-1 gene in Apostichopus japonicus by transcriptome sequencing and RACE approaches (designated as AjAP-1). The full-length of AjAP-1 was of 2944Â bp including a 5â² untranslated region (UTR) of 201Â bp, a 3â² UTR of 1753Â bp and a putative open reading frame of 990Â bp encoding a polypeptide of 329 amino acid residues. Two representative domains of Jun and bZIP as well as two nuclear localization signals (NLSs) were also detected in deduced amino acid of AjAP-1. Spatial distribution expression indicated that AjAP-1 was ubiquitously expressed in all examined tissues with predominant expression in the body wall, moderate in the tube feet, respiratory tree and colemocytes and slightly weak in the intestine and longitudinal muscle. Time-course expression analysis in intestine and coelomocytes revealed that AjAP-1 both reached its peak expression at 4Â h after Vibrio splendidus challenge with a 2.6 and 8.2-fold increase compared to their control groups, respectively. Taken together, all these results suggested that AjAP-1 was a novel immune factor and might be involved in the processes of anti-bacteria response in sea cucumber.
