Actin is a spherical 43 kilo-Dalton protein that is found in many cell types. It belongs to the class of proteins known as [http://en.wikipedia.org/wiki/Motor_proteins motor proteins]. Motor proteins function in the movement of substances across a substrate by utilizing [http://en.wikipedia.org/wiki/Adenosine_triphosphate ATP] as an energy source. It is one of the most highly conserved proteins differing by no more than 20% in species ranging from yeast to humans. ("Mediation, Modulation and Consequences of Membrane-Cytoskeleton Interactions".) In an alignment of the 81 unique actin protein sequences, scientists found that 17.4% of positions in the consensus sequence are invariant in all actins, 35.6 % of positions are invariant or have a difference in only one of the 81 actins, and 40.4% of positions are invariant or have what are considered conservative changes (Review Article Molecular genetics of actin function) | Actin is a spherical 43 kilo-Dalton protein that is found in many cell types.
