Insect transferrins: Multifunctional proteins
Biochimica et Biophysica Acta (BBA) - General Subjects, 2012Many studies have been done evaluating transferrin in insects. Genomic analyses indicate that insects could have more than one transferrin. However, the most commonly studied insect transferrin, Tsf1, shows greatest homology to mammalian blood transferrin.Aspects of insect transferrin structure compared to mammalian transferrin and the roles ...

Odorant-binding proteins in insects
Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1995This paper reviews the characteristics of pheromone and odorant-binding proteins (OBP) in insects, with particular reference to Lepidoptera. They are small (15 kDa) soluble proteins, very concentrated in the lymph of chemosensory sensilla and belonging to two major classes, pheromone-binding proteins (PBP) and general odorant-binding proteins.

Insects as an Alternative Protein Source
Annual Review of Food Science and Technology, 2022The recent COVID-19 pandemic drastically affected food supply chains worldwide, showing the vulnerability of food security. Efforts to develop alternative protein sources that are sustainable and can help alleviate global food shortage problems should be prioritized.

The respiratory proteins of insects
Journal of Insect Physiology, 2007For a long time, respiratory proteins have been considered unnecessary in most insects because the tracheal system was thought to be sufficient for oxygen supply. Only a few species that survive under hypoxic conditions were known exceptions. However, recently it has become evident that (1) intracellular hemoglobins belong to the standard repertoire of

Insect Defense Proteins and Peptides
2020The composition of insect hemolymph can change depending on many factors, e.g. access to nutrients, stress conditions, and current needs of the insect. In this chapter, insect immune-related polypeptides, which can be permanently or occasionally present in the hemolymph, are described.

Insects are the most abundant and diverse group of animals on earth. Therefore, it is not surprising that they have evolved numerous, generally non-mutually exclusive, adaptations to permit survival at subzero temperatures. In general, these adaptations can be divided into those that prevent freezing of freeze susceptible species (freeze avoidance) and

Membrane Protein Production in Insect Cells
2022Membrane proteins are an essential part of the machinery of life. They connect the interior and exterior of cells, play an important role in cell signaling and are responsible for the influx and efflux of nutrients and metabolites. For their structural and functional analysis high yields of correctly folded and modified protein are needed. Insect cells,

Publisher Summary This chapter discusses the structure and function of major groups of hemolymph proteins that are common to all insects, storage proteins, lipoproteins, vitellogenins, and inducible antibacterial proteins. It also discusses some proteins and peptides that are present in smaller amounts, sometimes occurring only in a few insect ...

Gel filtration of insect haemolymph proteins
Canadian Journal of Zoology, 1968Haemolymph from 6th instar larvae of Malacosoma americanum and 5th instar nymphs of Locusta migratoria was subjected to gel filtration on Sephadex G-200. Three protein fractions were produced in each case. Each fraction was analyzed for protein content and assayed for esterase and tyrosinase activity.

Thioester-containing proteins and insect immunity
Molecular Immunology, 2004Here, we discuss the role of thioester-containing proteins in innate immune responses of insects. TEPs are represented by multi-member families both in the fruitfly, Drosophila melanogaster, and in the mosquito, Anopheles gambiae. Phylogenetic analysis of the family suggests that in these two dipteran species evolution of TEPs followed independent ...
