A novel TAB2 gene (LvTAB2) is identified from pacific white shrimp Litopenaeus vannamei.
LvTAB2 is ubiquitously distributed and highly expressed in muscle.
LvTAB2 expression is induced by challenges of different immune stimuli.
LvTAB2 is involved in the regulation of antimicrobial peptide genes and Vago genes.
LvTAB2 plays an important role in the shrimp innate immune defense against V. parahaemolyticus and WSSV infection.
