Toxoplasma gondii

Toxoplasma gondii is an obligate intracellular parasitic protozoan that causes toxoplasmosis. Found worldwide, T. gondii is capable of infecting virtually all warm-blooded animals, but felids, such as domestic cats, are the only known definitive hosts in which the parasite may undergo sexual reproduction.

Domain of unknown function

A domain of unknown function (DUF) is a protein domain that has no characterised function. These families have been collected together in the Pfam database using the prefix DUF followed by a number, with examples being DUF2992 and DUF1220. As of 2019

Polyglutamine tract

Repeated sequence (DNA)

Repeated sequences are patterns of nucleic acids that occur in multiple copies throughout the genome. Repetitive DNA was first detected because of its rapid re-association kinetics. In many organisms, a significant fraction of the genomic DNA is highly

Plasmodium helical interspersed subtelomeric protein

The Plasmodium helical interspersed subtelomeric proteins (PHIST) or ring-infected erythrocyte surface antigens (RESA) are a family of protein domains found in the malaria-causing Plasmodium species. It was initially identified as a short four-helical

Flagellin

Flagellin is a globular protein that arranges itself in a hollow cylinder to form the filament in a bacterial flagellum. It has a mass of about 30,000 to 60,000 daltons. Flagellin is the principal component of bacterial flagella, and is present in large
