Protein attributes
| Sequence length | 542 AA. |
| Sequence status | Complete. |
| Protein existence | Evidence at protein level |
General annotation (Comments)
| Function | Acts as a tumor suppressor. Inhibits DNA synthesis. Its ability to inhibit oncogenic transformation is mediated through its association with RB1. Plays a role in the expression of genes required for the G1/S transition. Ref.1 Ref.2 |
| Subunit structure | Component of the DREAM complex (also named LINC complex) at least composed of E2F4, E2F5, LIN9, LIN37, LIN52, LIN54, MYBL1, MYBL2, RBL1, RBL2, RBBP4, TFDP1 and TFDP2. The complex exists in quiescent cells where it represses cell cycle-dependent genes. It dissociates in S phase when LIN9, LIN37, LIN52 and LIN54 form a subcomplex that binds to MYBL2. Interacts with RB1. Ref.1 Ref.6 Ref.7 |
| Subcellular location | Nucleus › nucleoplasm. Note: Found in perinucleolar structures. Associated with chromatin. Ref.1 Ref.2 |
| Tissue specificity | Expressed in thymus and testis. Ref.1 |
| Sequence similarities | Belongs to the lin-9 family. |
| Sequence caution | The sequence AAH43444.1 differs from that shown. Reason: Erroneous initiation. The sequence CAD97871.1 differs from that shown. Reason: Erroneous initiation. |
