    Summary
    Megakaryocytopoiesis is the cellular development process that leads to platelet production. The main functional protein encoded by this gene is a humoral growth factor that is necessary for megakaryocyte proliferation and maturation, as well as for thrombopoiesis. This protein is the ligand for MLP/C_MPL, the product of myeloproliferative leukemia virus oncogene. Mutations in this gene are the cause of thrombocythemia 1. Alternative promoter usage and differential splicing result in multiple transcript variants differing in the 5' UTR and/or coding region. Multiple AUG codons upstream of the main open reading frame (ORF) have been identified, and these upstream AUGs inhibit translation of the main ORF at different extent. [provided by RefSeq, Feb 2014]
    Annotation information
    Note: TPO (Gene ID: 7173) and THPO (Gene ID: 7066) share the TPO symbol/alias in common. TPO is a widely used alternative name for thrombopoietin (THPO), which can be confused with the official symbol for TPO, thyroid peroxidase. [27 Jun 2018]

    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.

    Suppressed Reference Sequence(s)

    The following Reference Sequences have been suppressed. Explain

    1. NM_199228.1: Suppressed sequence

      Description
      NM_199228.1: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.

    2. NM_199356.1: Suppressed sequence

      Description
      NM_199356.1: This RefSeq was permanently suppressed because currently there is insufficient support for the transcript and the protein.
