GeneRIFs: Gene References Into Functions

What's a GeneRIF?

By using chimeric mutant peropsins, it was found that peropsin potentially generates an "active form" that drives G-protein signalling in the dark by binding to all-trans-retinal, and that the active form photo-converts to an inactive form containing 11-cis-retinal.

Title: A systematic gene-based screen of chr4q22-q32 identifies association of a novel susceptibility gene, DKK2, with the quantitative trait of alcohol dependence symptom counts.
Peropsin gene is not a common cause of retinitis pigmentosa or some related retinal degenerations, at least in the set of patients we analyzed.

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.
