      Background InformationPontin/TIP49 (also known as Pontin 52, TIP49a, or 49 kDa TATA box-binding protein-interacting protein) is a member of the ruvB family. Members of this family are known to have ATP-dependent DNA helicase and a single-stranded, DNA-stimulated ATPase activities. Pontin participates in select transcriptional activation as a component of the NuA4 histone acetyltransferase complex that is thought to be necessary for the activation of specific transcription pathways related to oncogenesis. Pontin is a critical factor in cell proliferation and, when present on the cell surface, may bind to plasminogen and upregulate the activation of plasminogen. Expression of pontin is considered ubiquitous; however significantly high levels have been reported in skeletal muscle, testis, and heart tissue.

      UniProt Number
      UniProt SummaryFUNCTION: Possesses single-stranded DNA-stimulated ATPase and ATP-dependent DNA helicase (3' to 5') activity. Component of the NuA4 histone acetyltransferase complex which is involved in transcriptional activation of select genes principally by acetylation of nucleosomal histones H4 and H2A. This modification may both alter nucleosome - DNA interactions and promote interaction of the modified histones with other proteins which positively regulate transcription. This complex may be required for the activation of transcriptional programs associated with oncogene and proto-oncogene mediated growth induction, tumor suppressor mediated growth arrest and replicative senescence, apoptosis, and DNA repair. The NuA4 complex ATPase and helicase activities seem to be, at least in part, contributed by the association of RUVBL1 and RUVBL2 with EP400. NuA4 may also play a direct role in DNA repair when recruited to sites of DNA damage. RUVBL1 plays an essential role in oncogenic transformation by MYC and also modulates transcriptional activation by the LEF1/TCF1-CTNNB1 complex.

      May be able to bind plasminogen at cell surface and enhance plasminogen activation.

      Essential for cell proliferation.

      CATALYTIC ACTIVITY: ATP + H2O = ADP + phosphate.

      SUBUNIT STRUCTURE: Forms homotypic and heterotypic interactions. Forms a multimeric complex with RUVBL2. Interacts with the transcriptional activation domain of MYC. Component of the RNA polymerase II holoenzyme complex. May also act to bridge the LEF1/TCF1-CTNNB1 complex and TBP. Component of the NuA4 histone acetyltransferase complex which contains the catalytic subunit KAT5/TIP60 and the subunits EP400, TRRAP/PAF400, BRD8/SMAP, EPC1, DMAP1/DNMAP1, RUVBL1/TIP49, RUVBL2, ING3, actin, ACTL6A/BAF53A, MORF4L1/MRG15, MORF4L2/MRGX, MRGBP, YEATS4/GAS41, VPS72/YL1 and MEAF6. The NuA4 complex interacts with MYC and the adenovirus E1A protein. RUVBL1 interacts with EP400. Component of a NuA4-related complex which contains EP400, TRRAP/PAF400, SRCAP, BRD8/SMAP, EPC1, DMAP1/DNMAP1, RUVBL1/TIP49, RUVBL2, actin, ACTL6A/BAF53A, VPS72 and YEATS4/GAS41. Component of the BAF53 complex, at least composed of ACTL6A/BAF53A, RUVBL1/TIP49, SMARCA2/BRM, and TRRAP/PAF400. Component of some MLL1/MLL complex, at least composed of the core components MLL, ASH2L, HCFC1/HCF1, WDR5 and RBBP5, as well as the facultative components C17orf49, CHD8, E2F6, HSP70, IN80C, KIAA1267, LAS1L, MAX, MCRS1, MGA, MYST1/MOF, PELP1, PHF20, PRP31, RING2, RUVB1/TIP49A, RUVB2/TIP49B, SENP3, TAF1, TAF4, TAF6, TAF7, TAF9 and TEX10. Associates with alpha and gamma tubulins, particularly during metaphase and early anaphase. Interacts with NPAT. Component of the chromatin-remodeling INO80 complex, at least composed of ACTL6A, ACTR5, ACTR8, RVBL1, RVBL2, INO80, INO80B, INO80C, INO80D and INO80E. Interacts with IGHMBP2. Interacts with OFD1.

      SUBCELULAR LOCATION: Nucleus matrix. Nucleus › nucleoplasm. Cytoplasm. Membrane. Cytoplasm › cytoskeleton › centrosome. Note: Mainly localized in the nucleus, associated with nuclear matrix or in the nuclear cytosol, although it is also present in the cytoplasm and associated with the cell membranes. In prophase and prometaphase it is located at the centrosome and the branching microtubule spindles. After mitotic nuclear membrane disintigration it accumulates at the centrosome and sites of tubulin polymerization. As cells pass through metaphase and into telophase it is located close to the centrosome at the early phase of tubulin polymerization. In anaphase it accumulates at the zone of tubule interdigitation. In telophase it is found at polar tubule overlap, and it reappears at the site of chromosomal decondensation in the daughter cells.

      TISSUE SPECIFICTY: Ubiquitously expressed with high expression in heart, skeletal muscle and testis.

      DOMAIN: Binding to MYC is dependent on a Myc domain essential for oncogenic activity.

      MISCELLANEOUS: High level of autoantibodies against RUVBL1 are detected in sera of patients with autoimmune diseases such as polymyositis/dermatomyosistis and autoimmune hepatitis.

      SEQUENCE SIMILARITIES: Belongs to the ruvB family.
