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).

What's a GeneRIF?

PEX2 is required for peroxisome autophagy during starvation.
Title: PEX2 is the E3 ubiquitin ligase required for pexophagy during starvation.
Data indicate that the induction of SREBP-2 and ER stress pathways is independent of PPARalpha activation in livers of newborn peroxisome assembly factor 1 (Pex2) knockout mice.
Title: Peroxisome deficiency-induced ER stress and SREBP-2 pathway activation in the liver of newborn PEX2 knock-out mice.

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.
