In lecture we talked about the rationale of why some proteins are conserved over the course of evolution. What were three reasons we gave why actin is conserved?

Actin:

Actin is the most abundant protein in the eukaryotic cell. Actin are highly conserved because it is essential for all the organism to provide the proteins. Due to the pathogen entering in our body at first it affect the actin cytoskeleton or it is taken over by the numerous pathogen. Actin is the important body building structure in our body to maintain the important cellular process in our body. The process including muscle contraction, cell motality, cell division and cytokinesis. Actin is the highly conserved globular protein found in almost all eukaryotic cells.
