Target
Function
Component of the RNF20/40 E3 ubiquitin-protein ligase complex that mediates
monoubiquitination of 'Lys-120' of histone H2B (H2BK120ub1). H2BK120ub1 gives a specific
tag for epigenetic transcriptional activation and is also prerequisite for histone H3 'Lys-4' and
'Lys-79' methylation (H3K4me and H3K79me, respectively). It thereby plays a central role inb
histone code and gene regulation. The RNF20/40 complex forms a H2B ubiquitin ligase
complex in cooperation with the E2 enzyme UBE2A or UBE2B; reports about the cooperation
with UBE2E1/UBCH are contradictory. Required for transcriptional activation of Hox genes.
Recruited to the MDM2 promoter, probably by being recruited by p53/TP53, and thereby acts as
a transcriptional coactivator. Mediates the polyubiquitination of isoform 2 of PA2G4 in cancer
cells leading to its proteasome-mediated degradation.
Tissue specificity
Expressed in the normal brain and also in malignant gliomas (at protein level).
Pathway
Protein modification; protein ubiquitination.
Sequence similarities
Belongs to the BRE1 family.
Contains 1 RING-type zinc finger.
Cellular localization
Nucleus.

Detection of Human RNF20 by
Immunoprecipitation in Whole cell lysate from
HeLa cells (1 mg for IP, 20% of IP loaded)
using ab70495 at 3 µg/mg lysate.
Subsequent RNF20 WB detection was
performed using ab70495 at 1 µg/ml.
Immunoprecipitation - RNF20 antibody (ab70495)
ab70495 (1/1000) detecting RNF20 in HeLa
cells (green). Cells were fixed in
paraformaldehyde, permeabilised with 0.5%
Triton X100/PBS and counterstained with
DAPI in order to highlight the nucleus (red).
