GeneRIFs: Gene References Into Functions

What's a GeneRIF?

Loss of Zar1 causes marked upregulation of zona pellucida (ZP) family proteins, while overexpression of ZP proteins in oocytes causes upregulation of stress-related activating transcription factor 3 (atf3), arguing that tightly controlled translation of ZP proteins is essential for ER homeostasis during early oogenesis. Furthermore, Zar1 binds to ZP gene mRNAs and represses their translation.
Title: Translation repression by maternal RNA binding protein Zar1 is essential for early oogenesis in zebrafish.
The carboxyl-termini of these ZAR1 proteins contain an important functional domain that is conserved through vertebrate evolution and that may be necessary for normal female reproduction in the transition from oocyte to embryonic life.
Title: Zygote arrest 1 (Zar1) is an evolutionarily conserved gene expressed in vertebrate ovaries.

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.
