Peroxisomal Protein Targeting: A Step-by-Step Guide to PEX5, PEX7, and PEX19
The nucleus encodes all peroxisomal proteins because peroxisomes don’t contain their own DNA or ribosomes. The cell’s nuclear DNA encodes the genes for all peroxisomal proteins (e.g., catalase, the enzyme that breaks down hydrogen peroxide). These genes are transcribed into…
