The precursor of a mitochondrial matrix protein is found in a mutation in the tom22 signal receptor.
Tom22 and Tom20 function as N-terminal matrix targeting sequences' outer mitochondrial membrane receptor proteins. The buildup of mitochondrial matrix-targeted proteins in the cytosol due to a malfunctioning Tom22 receptor protein may be followed by cytosolic turnover of these proteins.
The N-terminal sequence, which directs the protein to mitochondria and is proteolytically processed upon import3, is produced in approximately 70% of mitochondrial precursor proteins3. To get to the matrix, they must pass via the TIM23 and TOM complexes on the inner and outer membranes, respectively.

Cells are so small so the surface area and volume of them can be proportional to each other. This helps with the efficiency of the cell's absorption and waste expulsion processes. Also by the cell's smallness, communication from the nucleus to other organelles is fast and the cell can be regulated while the conditions for diffusion are still ideal.Its because they need to be able to diffuse through materials easily. Also, materials inside and outside of the cell need to easily pass through the cell membrane, which makes it harder and slower for the materials to pass through the cell membrane.
