What's a GeneRIF?
  1. The ovarian phenotypes of these mice suggested that the MIGA1/2 proteins play an important role in ovulation and ovarian steroidogenesis. In vivo and in vitro analyses of Miga1/2-knockout granulosa cells showed severe defects in luteinization and steroidogenesis and disordered mitochondrial morphology and function in response to gonadotropins.

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.
