    Summary
    Acts upstream of or within negative regulation of cell population proliferation; negative regulation of mitotic nuclear division; and traversing start control point of mitotic cell cycle. Located in kinetochore. Is expressed in cerebellum; cerebral cortex subventricular zone; midbrain ventricular layer; olfactory cortex ventricular layer; and telencephalon ventricular layer. Orthologous to human MTBP (MDM2 binding protein). [provided by Alliance of Genome Resources, Dec 2024]

    What's a GeneRIF?
    1. Mtbp haploinsufficiency significantly increased longevity and maximal survival in mice. Reduced levels of Mtbp did not alter locomotor activity, litter size, or body size, but Mtbp heterozygous mice did exhibit elevated markers of metabolism, particularly in the liver. Mtbp(+/-) mice also had a significant delay in spontaneous cancer development
      Title: Haploinsufficiency of the Myc regulator Mtbp extends survival and delays tumor development in aging mice.
    2. Mtbp functioned independent of Mdm2 and was a limiting factor for the proliferative and transforming functions of Myc. Thus, Mtbp is a previously unrecognized regulator of Myc-induced tumorigenesis.

    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.
