Sheep anti Human, Rat E1A (adenovirus early region 1)

Sheep anti Human, Rat E1A (adenovirus early region 1), Polyclonal, IgG

Background: The immunogen for the anti-EIA was a recombinant E1A protein recognizing a 43kD protein. EIA gene encodes potent onco-proteins that modify the normal transcriptional growth regulation of key cellular genes and thus alter cell cycle control. E1A protein has both transforming and trans-activating activities. Plays a role in viral genome replication by driving entry of quiescent cells into the cell cycle. Disrupts the function of host retinoblastoma protein RB1/pRb and isoform early E1A 26 kDa protein stabilizes TP53, which are key regulators of the cell cycle. Induces the disassembly of the E2F1 transcription factors from RB1 by direct competition for the same binding site on RB1, with subsequent transcriptional activation of E2F1-regulated S-phase genes. Inactivation of the ability of RB1 to arrest the cell cycle is critical for cellular transformation, uncontrolled cellular growth and proliferation induced by viral infection. Stimulation of progression from G1 to S phase allows the virus to efficiently use the cellular DNA replicating machinery to achieve viral genome replication. Interaction with RBX1 and CUL1 inhibits ubiquitination of the proteins targeted by SCF(FBW7) ubiquitin ligase complex, and may be linked to unregulated host cell proliferation. The tumorigenesis-restraining activity of E1A may be related to the disruption of the host CtBP-CtIP complex through the CtBP binding motif

Positive Control: 293 cells are human embryonic kidney cells that have been transformed with the adenovirus genes E1A and E1B, which are required for adenovirus propagation. This cell line can be used as a positive control for this antibody. This antibody is suitable for use with his tagged or gst tagged recombinant proteins.
