    Summary
    This gene encodes a protein that is likely to function in progression of meiosis. A similar protein in mouse plays a role in gametogenesis in both sexes. Alternate splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2013]

    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.

    1. NM_001281295.2 → NP_001268224.1  meiosis 1 arrest protein isoform 2

      Status: REVIEWED

      Description
      Transcript Variant: This variant (2) contains an alternate exon in the 5' UTR, lacks several exons at its 3' end, and its 3' terminal exon extends past a splice site that is used in variant 1. This results in a novel 3' coding region and 3' UTR, compared to variant 1. It encodes isoform 2 which is shorter and has a distinct C-terminus compared to isoform 1.

      Transcript Variant: This variant (3) contains an alternate exon in the 5' UTR and lacks an in-frame exon in the 3' coding region compared to variant 1. The resulting protein (isoform 3) is shorter than isoform 1.
