X-ray crystallographic studies on structure and fucntion of hemocyanins. [PDF]

, 1993
Hemocyanin is the oxygen transport pigment in many arthropods and molluscs. In this respect, hemocyanin has the same function as hemoglobin has in many other organisms.

Cryo-EM structure of isomeric molluscan hemocyanin triggered by viral infection. [PDF]

PLoS ONE, 2014
Hemocyanins (Hcs) of arthropods and mollusks function not only as oxygen transporters, but also as phenoloxidases (POs). In invertebrates, PO is an important component in the innate immune cascade, where it functions as the initiator of melanin synthesis,

Protein-Level Evidence of Novel β-Type Hemocyanin and Heterogeneous Subunit Usage in the Pacific Whiteleg Shrimp, Litopenaeus vannamei

Frontiers in Marine Science, 2019
The functional diversity of crustacean hemocyanins is broad, encompassing O2 delivery, innate immune response, metabolite storage, and osmolyte balance, all in a heterogeneous protein structure.

Calorimetric Study of Helix aspersa Maxima Hemocyanin Isoforms

Journal of Analytical Methods in Chemistry, 2018
The thermal unfolding of hemocyanin isoforms, β-HaH and αD+N-HaH, isolated from the hemolymph of garden snails Helix aspersa maxima, was studied by means of differential scanning calorimetry (DSC). One transition, with an apparent transition temperature (

Quanternary structure of multihexameric arthropod hemocyanins

, 1994
Arthropod hemocyanins are large oligomeric oxygen-transporting proteins with molecular weight ranging from 450 kDa in the spiny lobster (Panulirus interruptus) up to more than 3.6 mDa in the horseshoe crab (Limulus polyphemus). Hemocyanins from different

The RNA‐Binding Protein PARN Remodeled 3′ UTR Structure Defines Poly(A)‐Loading Sites to Mediate Immunoglobulin Homeostasis

Advanced Science, EarlyView.
ABSTRACT Class Switch Recombination (CSR) is essential for generating high‐affinity antibody isotypes from IgM during adaptive humoral responses. Despite well‐established roles for various transcription factors, whether CSR is subject to dedicated post‐transcriptional control represents a significant gap in knowledge.

NFYB Integrates Hormonal Signals into Tissue Allometry by Promoting Protein Biosynthesis

Advanced Science, EarlyView.
In the American cockroach, NFYB acts as a spatiotemporin that translates distinct hormonal cues into tissue‐specific allometry. Juvenile hormone activates NFYB in the early fat body, while 20‐hydroxyecdysone induces it in late wing pads. NFYB then promotes protein biosynthesis via core translational machinery, driving differential growth across the ...

Chemically Modified Hemocyanins with Enhanced Antibreast Cancer Activities

Proceedings, 2019
Some cancer cells hyperexpress folate receptors (FR); therefore, folate-derivatized deliverysystems are applied for a selective delivery of chemotherapeutics. [...]
