What's a GeneRIF?

TSPO ligands can induce Plasmodium falciparum death by increasing the uptake of porphyrins through a TSPO2-VDAC complex, which leads to an accumulation of reactive oxygen species.

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.
