제품 세부 정보

What are recombinant multiclonals?
Recombinant multiclonals are a mixture of recombinant antibodies co-expressed from a library of heavy and light chains. They offer several advantages including:

  • - The sensitivity of polyclonal antibodies by recognising multiple epitopes
  • - High batch-to-batch consistency and reproducibility
  • - Improved sensitivity and specificity
  • - Long-term security of supply
  • - Animal-free batch production

Retinoblastoma protein (Rb) also known as pRb is an important regulatory protein with a molecular weight of approximately 110 kDa. It is mainly expressed in the nucleus of cells. Rb functions as a tumor suppressor by controlling the cell cycle progression from G1 to S phase. Rb becomes active when it is dephosphorylated allowing it to bind and inhibit E2F transcription factors consequently preventing the transcription of genes essential for S phase entry.
Biological function summary

Retinoblastoma protein influences cellular proliferation differentiation and apoptosis. It acts within a larger protein complex modulating various cellular responses. When functional Rb halts uncontrolled cell division important for maintaining normal tissue homeostasis. In its phosphorylated state known as phospho-Rb or phospho-Rb E182 it loses its regulatory capabilities which can lead to unrestrained cell cycle progression.

Pathways

Several involve the retinoblastoma protein. One key pathway is the p53 pathway which Rb interacts with to influence cellular outcomes like cell-cycle arrest and apoptosis. Rb cooperates with proteins like p21 to implement these processes. Additionally it is involved in the cyclin D-dependent kinase 4 (CDK4) pathway which modulates its phosphorylation state influencing binding interactions and cell cycle control.

Dysregulation of retinoblastoma protein is commonly associated with cancer particularly retinoblastoma and breast cancer. In retinoblastoma mutations in the Rb gene directly lead to uncontrolled cell proliferation due to the absence of functional Rb protein. Additionally Rb's connection to the E2F family of transcription factors can become disrupted contributing to oncogenesis in other cancers.

타겟 정보

Tumor suppressor that is a key regulator of the G1/S transition of the cell cycle (PubMed : 10499802). The hypophosphorylated form binds transcription regulators of the E2F family, preventing transcription of E2F-responsive genes (PubMed : 10499802). Both physically blocks E2Fs transactivating domain and recruits chromatin-modifying enzymes that actively repress transcription (PubMed : 10499802). Cyclin and CDK-dependent phosphorylation of RB1 induces its dissociation from E2Fs, thereby activating transcription of E2F responsive genes and triggering entry into S phase (PubMed : 10499802). RB1 also promotes the G0-G1 transition upon phosphorylation and activation by CDK3/cyclin-C (PubMed : 15084261). 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 SUV39H1, KMT5B and KMT5C, leading to epigenetic transcriptional repression. Controls histone H4 'Lys-20' trimethylation. Inhibits the intrinsic kinase activity of TAF1. Mediates transcriptional repression by SMARCA4/BRG1 by recruiting a histone deacetylase (HDAC) complex to the c-FOS promoter. In resting neurons, transcription of the c-FOS promoter is inhibited by BRG1-dependent recruitment of a phospho-RB1-HDAC1 repressor complex. Upon calcium influx, RB1 is dephosphorylated by calcineurin, which leads to release of the repressor complex (By similarity).. (Microbial infection) In case of viral infections, interactions with SV40 large T antigen, HPV E7 protein or adenovirus E1A protein induce the disassembly of RB1-E2F1 complex thereby disrupting RB1's activity.
