Background:

Myosins are essential molecular motors involved in various cellular processes.
Protists represent a diverse group of eukaryotic microorganisms with unique myosin repertoires.

Purpose of the Study:

To provide a historical perspective and current understanding of myosin structure and function in protists.
To catalog and describe myosin isoforms identified in various protist species.

Main Methods:

Literature review of selected papers on protist myosins.
Phylogenetic analysis of myosin classes.
Detailed examination of domain structure, cellular localization, function, and regulation of identified myosin isoforms.

Main Results:

A general overview of myosin structure and a phylogenetic tree of myosin classes are presented.
Specific myosin isoforms found in different protist groups are described.
The cellular roles and regulatory mechanisms of these protist myosins are elucidated.

Conclusions:

Protist myosins exhibit significant diversity in structure and function.
Understanding protist myosins provides insights into myosin evolution and cellular mechanics in eukaryotes.
