PEX13 (Peroxisomal Biogenesis Factor 13) is a Protein Coding gene. Diseases associated with PEX13 include Peroxisome Biogenesis Disorder 11B and Peroxisome Biogenesis Disorder 11A. Among its related pathways are Peroxisome. PEX13 encodes a peroxisomal membrane protein that binds the type 1 peroxisomal targeting signal receptor via a SH3 domain located in the cytoplasm. Mutations and deficiencies in peroxisomal protein importing and peroxisome assembly lead to peroxisomal biogenesis disorders, an example of which is Zellweger syndrome.
