What's a GeneRIF?

Notch ligand binding leads to gamma-secretase-mediated proteolytic cleavage of the Notch receptor releasing the Notch intracellular domain, resulting in its subsequent translocation into the nucleus and gene expression regulation
Title: Determination of relative Notch1 and gamma-secretase-related gene expression in puromycin-treated microdissected rat kidneys.
Pharmacogenetically bred apomorphine-susceptible Wistar rats have only one or two copies of the Aph-1b gene; in these rats, gamma-secretase activity is altered, leading to a complex phenotype.
Title: Reduced Aph-1b expression causes tissue- and substrate-specific changes in gamma-secretase activity in rats with a complex phenotype.
Aph1b and KCnIP1 are significantly differentially expressed in a number of brain tissues of a schizophrenia model; KCnIP1 is an attractive novel candidate gene that may play a role in the complex phenotype
Title: Gene expression profiling in brain regions of a rat model displaying schizophrenia-related features.
low levels of Aph-1b mRNA and gamma-secretase activity observed in the I/I and II/II rats during the entire developmental period may well underlie their complex phenotype
Title: Ontogenic reduction of Aph-1b mRNA and gamma-secretase activity in rats with a complex neurodevelopmental phenotype.

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.
