| 产品介绍 | background: The pocket protein family consists of three structurally and functionally related proteins, Rb (retinoblastoma), p107, and p130. This family of tumor suppressors function to regulate important cellular transcription factors, such as the E2F family. The E2F proteins regulate the expression of genes whose products are important for cell cycle progression. The inactivation Rb is catalyzed by CDK phosphorylation thereby releasing E2F during the G1-S phase cellular progression. Unchecked inactivation of Rb in G1 phase has been indicated as a universal mechanism underlying cellular transformation . While Rb has been the most studied among the pocket proteins, p107 and p130 have also been shown to be key regulators of E2F. Several studies have also provided evidence that p107/p130 provide different functions in E2F regulation than does Rb. Rb, p107, and p130 each contain a conserved 'A/B pocket', which is the target of several viral oncoproteins, namely SV40 large T-antigen and adenovirus E1A. There are two isoforms. Function: Key regulator of entry into cell division. Directly involved in heterochromatin formation by maintaining overall chromatin structure and, in particular, that of constitutive heterochromatin by stabilizing histone methylation. Recruits and targets histone methyltransferases SUV420H1 and SUV420H2, leading to epigenetic transcriptional repression. Controls histone H4 'Lys-20' trimethylation. Probably acts as a transcription repressor by recruiting chromatin-modifying enzymes to promoters. Potent inhibitor of E2F-mediated trans-activation. Forms a complex with adenovirus E1A and with SV40 large T antigen. May bind and modulate functionally certain cellular proteins with which T and E1A compete for pocket binding. May act as a tumor suppressor. Subunit: Interacts with SUV420H1, SUV420H2 and USP4 (By similarity). 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 AATF. Interacts with KDM5A. Interacts with SV40 and JC virus large T antigens. Subcellular Location: Nucleus. Post-translational modifications: Exists in both phosphorylated and unphosphorylated forms, and T, but not E1A, binds only to the unphosphorylated form. Cell-cycle arrest properties are inactivated by phosphorylation on Thr-332, Ser-640, Ser-964 and Ser-975 by CDK4. Similarity: Belongs to the retinoblastoma protein (RB) family.

口袋蛋白家族由三个结构和功能相关的蛋白，Rb（视网膜母细胞瘤），P107和P130组成。这一家族的肿瘤抑制因子的功能调节重要的细胞转录因子，如E2F家族。E2F蛋白调节基因的表达，其产物对于细胞周期进程是重要的。失活Rb由CDK磷酸化催化，从而在G1-S期细胞进程中释放E2F。未检测到的Rb在G1期的失活已被证明是细胞转化的普遍机制。虽然Rb一直是囊泡蛋白中最被研究的，P107和P130也被证明是E2F的关键调节因子。一些研究还提供了证据表明P107/P130在E2F调节中提供了不同于Rb的功能。Rb、P107和P130均含有保守的“A/B口袋”，这是几种病毒癌蛋白的靶点，即SV40大T抗原和腺病毒E1A。
