Identification, functional analysis of chitin-binding proteins and the association of its single nucleotide polymorphisms with Vibrio parahaemolyticus resistance in Penaeus vannamei.

Chitin-binding proteins (CBPs) play pivotal roles in numerous biological processes in arthropods, including growth, molting, reproduction, and immune defense. However, their function in the antibacterial immune defense of crustaceans remains relatively underexplored. In this study, twenty CBPs were identified and characterized in Penaeus vannamei.

Genome-wide analysis of ATP-binding cassette (ABC) transporter in Penaeus vannamei and identification of two ABC genes involved in immune defense against Vibrio parahaemolyticus by affecting NF-κB signaling pathway.

The ATP-binding cassette (ABC) transporters have crucial roles in various biological processes such as growth, development and immune defense in eukaryotes. However, the roles of ABC transporters in the immune system of crustaceans remain elusive. In this study, 38 ABC genes were systematically identified and characterized in Penaeus vannamei.
