General annotation (Comments)
| Function | E3 ubiquitin-protein ligase which accepts ubiquitin from an E2 ubiquitin-conjugating enzyme in the form of a thioester and then directly transfers the ubiquitin to targeted substrates. Polyubiquitinates POU5F1 by 'Lys-63'-linked conjugation and promotes it to proteasomal degradation; in embryonic stem cells (ESCs) the ubiquitination is proposed to regulate POU5F1 protein level. Ubiquitinates EGR2 and promotes it to proteasomal degradation; in T-cells the ubiquitination inhibits activation-induced cell death. Ubiquitinates SLC11A2; the ubiquitination is enhanced by presence of NDFIP1 and NDFIP2. Ubiquitinates RPB1 and promotes it to proteasomal degradation. Ref.13 Ref.15 |
| Enzyme regulation | Activated by NDFIP1- and NDFIP2-binding. |
| Pathway | |
| Subunit structure | Interacts with POU5F1, RBP1, EGR2 and SLC11A2 By similarity. Interacts with SCNN1A, SCNN1B, SCNN1G, WBP1, WBP2, ATN1 and adenovirus type 2 PIII. Interacts with ERBB4, NDFIP1 AND NDFIP2. Ref.1 Ref.7 Ref.8 Ref.9 Ref.10 Ref.13 Ref.15 Ref.16 |
| Subcellular location | |
| Tissue specificity | Detected in heart, throughout the brain, placenta, lung, liver, muscle, kidney and pancreas. Also detected in spleen and peripheral blood leukocytes. Ref.7 Ref.13 |
| Developmental stage | Highly expressed in undifferentiated embryonic stem cells and expression is reduced after embryoid body (EB) formation. Not detectable at day 13 of EB formation; low levels are again detected at day 18 of EB formation. Ref.13 |
| Domain | The C2 domain is involved in autoinhibition of the catalytic activity by interacting with the HECT domain By similarity. Ref.12 |
| Post-translational modification | Autoubiquitinated. Ubiquitinated by the SCF(FBXL15) complex, leading to its degradation by the proteasome. Ref.14 Ref.18 |
| Miscellaneous | A cysteine residue is required for ubiquitin-thioester formation. |
| Sequence similarities | Contains 1 C2 domain. Contains 1 HECT (E6AP-type E3 ubiquitin-protein ligase) domain. Contains 4 WW domains. |
| Sequence caution | The sequence BAC86528.1 differs from that shown. Reason: Frameshift at position 757. |
