    Summary
    Predicted to enable ubiquitin protein ligase activity. Involved in peroxisome organization. Acts upstream of or within several processes, including bile acid biosynthetic process; cholesterol homeostasis; and regulation of cholesterol biosynthetic process. Predicted to be located in peroxisome. Predicted to be part of Cdc73/Paf1 complex. Predicted to be active in peroxisomal membrane. Is expressed in several structures, including central nervous system and genitourinary system. Human ortholog(s) of this gene implicated in Peroxisome biogenesis disorder 5B and peroxisome biogenesis disorder 5A. Orthologous to human PEX2 (peroxisomal biogenesis factor 2).

    RefSeqs maintained independently of Annotated Genomes

    These reference sequences exist independently of genome builds. Explain

    These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
