    4. EEFSEC, which encodes selenocysteine-tRNA specific eukaryotic elongation factor, participates in the incorporation of selenocysteine into selenoproteins. Selenoproteins serve critical cellular homeostatic functions in maintaining redox status and antioxidant defenses, as well as modulating inflammatory responses. These physiologic functions have been linked to the parturition process and preterm birth.

    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.
