All UniProt accessions (4): Q9HAT8, A0A994J4T1, H0YK56, H0YNF4

UniProt curated annotations — full annotation on UniProt →

Function. E3 ubiquitin ligase catalyzing the covalent attachment of ubiquitin moieties onto substrate proteins. Involved in the TLR and IL-1 signaling pathways via interaction with the complex containing IRAK kinases and TRAF6. Mediates IL1B-induced IRAK1 ‘Lys-63’-linked polyubiquitination and possibly ‘Lys-48’-linked ubiquitination. May be important for LPS- and IL1B-induced MAP3K7-dependent, but not MAP3K3-dependent, NF-kappa-B activation. Can activate the MAP (mitogen activated protein) kinase pathway leading to activation of ELK1.

Subunit / interactions. Interacts with TRAF6, IRAK1, IRAK4 and MAP3K7. Interacts with BCL10; this interaction is impaired by SOCS3.

Post-translational modifications. Phosphorylated by IRAK1 and IRAK4 enhancing its E3 ligase activity.

Domain organisation. The atypical FHA domain contains a ‘wing’ insert and mediates binding to threonine-phosphorylated IRAK1.

Pathway. Protein modification; protein ubiquitination.

Similarity. Belongs to the pellino family.
