What's a GeneRIF?

These data identify DNase 2 as the predominant DNase on the mammalian skin surface and indicate that its activity is primarily targeted to exogenous DNA.
Title: DNase 2 is the main DNA-degrading enzyme of the stratum corneum.
DNase II-like acid DNase is synthesized as a precursor with a signal sequence, and is localized to lysosomes. DNase II-like acid DNase mRNA was found in cortical fiber cells but not epithelial cells
Title: Degradation of nuclear DNA by DNase II-like acid DNase in cortical fiber cells of mouse eye lens.
gene lie head-to-head with the urate oxidase gene
Title: Isolation and characterization of the DLAD/Dlad genes, which lie head-to-head with the genes for urate oxidase.
The DLAD-/- mice develop cataracts of the nucleus lentis, and their response to light on electroretinograms is severely reduced; these results indicate that DLAD is responsible for the degradation of nuclear DNA during lens cell differentiation
Title: Nuclear cataract caused by a lack of DNA degradation in the mouse eye lens.

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.
