The evolutionary adaptation of shrimp hemocyanin subtypes and the consequences on their structure and functions.

Fish and Shellfish Immunology, 2023
Hemocyanin is the main respiratory protein of arthropods and is formed by hexameric and/or oligomeric subunits. Due to changes in the living environment and gene rearrangement, various hemocyanin subtypes and subunits evolved in crustaceans.

Molluscan Hemocyanins

2020
Instead of the red blood of vertebrates, most molluscs have blue hemolymph containing hemocyanin, a type-3 copper-containing protein. The hemoglobin of vertebrate blood is replaced in most molluscs with hemocyanin, which plays the role of an  oxygen transporter.

Arachnid Hemocyanins

2020
Hemocyanin (Hc), a copper-containing extracellular multimeric protein, is the major protein component of hemolymph in different arachnid groups. Hc possesses 7 or 8 very well-characterized types of monomers with molecular weights ranging from 70 to 85 kDa, organized in hexamers or multiple of hexamers.

Responses of hemocyanin and energy metabolism to acute nitrite stress in juveniles of the shrimp Litopenaeus vannamei.

Ecotoxicology and Environmental Safety, 2019
Nitrite is a common toxic substance in culture systems of Litopenaeus vannamei, and the stress may disturb hemocyanin synthesis and energy metabolism and result in shrimp death.

Litopenaeus vannamei attenuates white spot syndrome virus replication by specific antiviral peptides generated from hemocyanin

Developmental and Comparative Immunology, 2019
Recent studies have shown that hemocyanin plays immune‐related functions apart from its canonical respiratory function. While shrimp hemocyanin is found to generate antimicrobial peptides, antiviral related peptides have not been reported. In the present

Bivalve hemocyanins—a comparison with other molluscan hemocyanins

Comparative Biochemistry and Physiology Part B: Comparative Biochemistry, 1988
1. The hemocyanins of the protobranch bivalves Yoldia thraciaeformis, Yoldia limatula and Acila castrensis have absorption spectra similar to other hemocyanins. 2. Hemocyanins from all three bivalves appear as six-tiered cylinders in the electron microscope (30-32 nm in diameter by 34-38 nm in height). Yoldia thraciaeformis and A.

Effects of Vibro harveyi and Staphyloccocus aureus infection on hemocyanin synthesis and innate immune responses in white shrimp Litopenaeus vannamei.

Fish and Shellfish Immunology, 2019
Hemocyanin, a multifunctional oxygen-carrying protein, has critical effects on immune defense in crustaceans. To explore the role of hemocyanin in anti-pathogen mechanism, effects of Vibrio harveyi (V. harvey) and Staphyloccocus aureus (S.

Analysis of Litopenaeus vannamei hemocyanin interacting proteins reveals its role in hemolymph clotting.

Journal of Proteomics, 2019
Hemocyanin is the main component of hemolymph plasma proteins and possesses diverse immunological properties and immunomodulatory functions. However, the interacting networks of hemocyanin in shrimp immune response remain poorly understood. In this study,

Multifunctional Roles of Hemocyanins

2020
The copper-containing hemocyanins are proteins responsible for the binding, transportation and storage of dioxygen within the blood (hemolymph) of many invertebrates. Several additional functions have been attributed to both arthropod and molluscan hemocyanins, including (but not limited to) enzymatic activity (namely phenoloxidase), hormone transport,
