General annotation (Comments)
| 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 in 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. Ref.7 Ref.8 |
| Pathway | |
| Subunit structure | Component of the RNF20/40 complex (also known as BRE1 complex) probably composed of 2 copies of RNF20/BRE1A and 2 copies of RNF40/BRE1B. Interacts with UBE2E1/UBCH6. Interacts with RB1 and WAC. Ref.1 Ref.7 Ref.8 Ref.10 |
| Subcellular location | |
| Tissue specificity | Ubiquitously expressed. Expressed at higher level in testis, heart and pancreas, while it is only weakly expressed in lung, skeletal muscle and small intestine. Ref.1 |
| Sequence similarities | Belongs to the BRE1 family. Contains 1 RING-type zinc finger. |
| Sequence caution | The sequence BAA31636.2 differs from that shown. Reason: Erroneous initiation. Translation N-terminally shortened. The sequence CAE45869.1 differs from that shown. Reason: Aberrant splicing. |
