What's a GeneRIF?

Study demonstrated that both TEX101 and Ly6k contribute mutually for their protein expression in the testicular germ cells, suggesting that the expression-balance of these two proteins is essential for fertile sperm formation.
Title: TEX101, a glycoprotein essential for sperm fertility, is required for stable expression of Ly6k on testicular germ cells.
LY6K is a newly identified factor involved in sperm fertilizing ability
Title: GPI-anchored protein complex, LY6K/TEX101, is required for sperm migration into the oviduct and male fertility in mice.
This information is essential for the molecular classification of Ly6k, and may help uncover the detailed physiological role of Ly6k in gametogenesis, or cancer biology.
Title: Molecular expression of Ly6k, a putative glycosylphosphatidyl-inositol-anchored membrane protein on the mouse testicular germ cells.
This study confirmed the biological interaction between TEX101 and Ly6k.
Title: TEX101, a germ cell-marker glycoprotein, is associated with lymphocyte antigen 6 complex locus k within the mouse testis.
Expression profiling confirmed that mLy-6K is expressed by plasma cells but not B cells or tissues not containing plasma cells.
Title: Identification of Ly-6K as a novel marker for mouse plasma cells.

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.
