What's a GeneRIF?

Results show prominent SMR3A expression in head and neck squamous cell carcinoma, which was accompanied by an up-regulation of ESR2. These data suggest a critical role of ESR2 in radio-resistance and that SMR3A might serve as a surrogate marker for active ESR2 signaling.
Title: Regulation of submaxillary gland androgen-regulated protein 3A via estrogen receptor 2 in radioresistant head and neck squamous cell carcinoma cells.
High SMR3A expression is associated with aberrant differentiation into mucosal- or glandular-like cells in Adenoid Cystic Carcinoma of the Head and Neck.

All members of the human opiorphin family of genes can potentially modulate erectile physiology. Both hSMR3 and ProL1 are down-regulated in the corpora of men with ED, and therefore both genes can potentially act as markers of ED.
Title: The opiorphin gene (ProL1) and its homologues function in erectile physiology.
Results suggest that hSMR3A can act as a marker for erectile dysfunction associated with both diabetic and non-diabetic etiologies.
Title: hSMR3A as a marker for patients with erectile dysfunction.

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.
