Summary
Predicted to be involved in homologous chromosome pairing at meiosis and meiotic attachment of telomere to nuclear envelope. Predicted to act upstream of or within meiosis I; oogenesis; and spermatogenesis. Predicted to be located in chromosome, telomeric region. Predicted to be active in nuclear inner membrane. Implicated in spermatogenic failure 59. [provided by Alliance of Genome Resources, Jul 2025]

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.
