What's a GeneRIF?

Findings broaden our knowledge of SPAG-1, showing that it exerts a role in oocyte meiotic execution via its involvement in AMPK and MAPK signaling pathways.
Title: The GTPase SPAG-1 orchestrates meiotic program by dictating meiotic resumption and cytoskeleton architecture in mouse oocytes.
The number of PCR positives of sperm mtDNA in two-cell embryos was significantly increased following sperm incubation with anti-tetratricopeptide repeat-containing protein involved in spermatogenesis (tpis).
Title: The sperm mitochondria-specific translocator has a key role in maternal mitochondrial inheritance.

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.

Status: VALIDATED

Description

Transcript Variant: This variant (7) lacks an alternate internal exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most expected translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
