The function of Ensembl gene identifier ENSG00000121680 (PEX16, peroxisomal biogenesis factor 16) is as follows. Required for peroxisome membrane biogenesis. May play a role in early stages of peroxisome assembly. Can recruit other peroxisomal proteins, such as PEX3 and PMP34, to de novo peroxisomes derived from the endoplasmic reticulum (ER). May function as receptor for PEX3. {ECO:0000269|PubMed:10704444, ECO:0000269|PubMed:12223482, ECO:0000269|PubMed:16717127}.
