What's a GeneRIF?

Authors provide evidence that PXMP2 is not essential for H2O2 permeation across the peroxisomal membrane, neither in control cells nor in cells lacking PEX11B, a peroxisomal membrane-shaping protein whose yeast homologue facilitates the permeation of molecules up to 400Da.
Title: Deciphering the potential involvement of PXMP2 and PEX11B in hydrogen peroxide permeation across the peroxisomal membrane reveals a role for PEX11B in protein sorting.

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.
