Vitellogenin Ab structure of the amazonian Arapaima gigas

General and Comparative Endocrinology, 2023
The vitellogenin is composed by polypeptides that are precursors of egg yolk proteins that provides embryo and larvae nutrition. The mRNA encoding for vitellogenin Ab (Vtg-Ab; 4,536 bp long and 1,512 amino acids) were obtained by RNA-Seq library sequencing of pirarucu gonads.

Identification of type II interferons and receptors in an osteoglossiform fish, the arapaima Arapaima gigas

Developmental & Comparative Immunology, 2023
In mammals, type II interferon (IFN; i.e. IFN-γ) signalling transduces through its specific receptors IFN-γR1 and IFN-γR2. In an osteoglossiform fish, the arapaima Arapaima gigas, three type II IFNs, IFN-γ-like, IFN-γ and IFN-γrel, and their four possible receptor subunits IFN-γR1-1, IFN-γR1-2, IFN-γR2-1 and IFN-γR2-2 were identified in this study.

Mechanical properties and the laminate structure of Arapaima gigas scales

Journal of the Mechanical Behavior of Biomedical Materials, 2011
The Arapaima gigas scales play an important role in protecting this large Amazon basin fish against predators such as the piranha. They have a laminate composite structure composed of an external mineralized layer and internal lamellae with thickness of 50-60 μm each and composed of collagen fibers with ~1 μm diameter.
