PmLT, a C-type lectin specific to hepatopancreas is involved in the innate defense of the shrimp Penaeus monodon.

A diverse class of proteins called lectins plays a major role in shrimp innate immunity. In this study, the cDNA encoding a C-type lectin of Penaeus monodon (PmLT) was cloned, and its potential role examined. Despite the low overall amino acid sequence identity with other animal lectins, PmLT includes conserved carbohydrate recognition domains (CRDs) characteristic of animal C-type lectins.

Molecular cloning of a C-type lectin (LvLT) from the shrimp Litopenaeus vannamei: early gene down-regulation after WSSV infection.

C-type lectin is one of the pattern-recognition proteins of the non-self innate immune system in the invertebrates. In this study, a lectin-like cDNA (LvLT) of Litopenaeus vannamei was cloned and characterized. LvLT cDNA consists of 1035 nt encoding for a protein with 345 amino acid residues.
