General annotation (Comments)
| Function | Core component of the DBIRD complex, a multiprotein complex that acts at the interface between core mRNP particles and RNA polymerase II (RNAPII) and integrates transcript elongation with the regulation of alternative splicing: the DBIRD complex affects local transcript elongation rates and alternative splicing of a large set of exons embedded in (A + T)-rich DNA regions. Inhibits SIRT1 deacetylase activity leading to increasing levels of p53/TP53 acetylation and p53-mediated apoptosis. Inhibits SUV39H1 methyltransferase activity. Ref.9 Ref.10 Ref.12 Ref.18 |
| Subunit structure | Component of the DBIRD complex. Interacts with ZNF326/ZIRD; the interaction is direct. Interacts (via N-terminus) with SIRT1. Interacts (via N-terminus) with SUV39H1; this interaction abolishes the interaction with SIRT1. Ref.9 Ref.10 Ref.12 Ref.18 |
| Subcellular location | Nucleus Probable. |
| Tissue specificity | Expressed ubiquitously in normal tissues. Expressed in 84 to 100% of neoplastic breast, lung, and colon tissues. Ref.7 |
| Sequence caution | The sequence AAG02472.1 differs from that shown. Reason: Frameshift at positions 610, 622, 794 and 810. The sequence BAB85553.1 differs from that shown. Reason: Erroneous initiation. |
