Anti-EDD / UBR5

Background

EDD / UBR5 (2,799 aa, 309 kDa) is E3 ubiquitin-protein ligase which is a component of the N-end rule pathway. Recognizes and binds to proteins bearing specific N-terminal residues that are destabilizing according to the N-end rule, leading to their ubiquitination and subsequent degradation By similarity. Involved in maturation and/or transcriptional regulation of mRNA by activating CDK9 by polyubiquitination. May play a role in control of cell cycle progression. May have tumor suppressor function. Regulates DNA topoisomerase II binding protein (TopBP1) in the DNA damage response. Plays an essential role in extraembryonic development. Ubiquitinates acetylated PCK1. Also acts as a regulator of DNA damage response by acting as a suppressor of RNF168, an E3 ubiquitin-protein ligase that promotes accumulation of 'Lys-63'-linked histone H2A and H2AX at DNA damage sites, thereby acting as a guard against excessive spreading of ubiquitinated chromatin at damaged chromosomes.

Application

 

Fig.1 Identification of EDD in whole cell extracts of human cells by western blotting using anti-EDD antibody.
Lane 1; HeLa cells transfected with control siRNA
Lane 2; HeLa cells transfected with EDD-specific siRNA
Lane 3; HEK293T cells transfected with pFlag-CMV-5b empty vector
Lane 4; HEK293T cells transfected with pCMV-Tag2b-EDD expression vector Predicted molecular mass of EDD is 309 kDa and the corresponding band in Lane 1 is much reduced in Lane 2 by introduction of the EDD-specific siRNA. Note that expression level of EDD in HEK293T cells is much higher than in HeLa cells. The data are by courtesy of Prof. M. Fujita of Kyushu University
