A myzozoan-specific protein is an essential membrane-anchoring component of the succinate dehydrogenase complex in parasites.

Succinate dehydrogenase (SDH) is a protein complex that functions in the tricarboxylic acid cycle and the electron transport chain of mitochondria. In most eukaryotes, SDH is highly conserved and comprises the following four subunits: SdhA and SdhB form the catalytic core of the complex, while SdhC and SdhD anchor the complex in the membrane. is an apicomplexan parasite that infects one-third of humans worldwide.
