Protein attributes

Sequence length	1572 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	E3 ubiquitin-protein ligase that mediates ubiquitination of TP73. Acts to stabilize TP73 and enhance activation of transcription by TP73. Ref.5
Pathway	Protein modification; protein ubiquitination.
Subunit structure	Interacts with TP73. Ref.5
Subcellular location	Cytoplasm By similarity.
Tissue specificity	Predominantly expressed in adult brain, lung and heart. Ref.5
Sequence similarities	Contains 1 C2 domain. Contains 1 HECT (E6AP-type E3 ubiquitin-protein ligase) domain. Contains 2 WW domains.
Sequence caution	The sequence BAA92539.1 differs from that shown. Reason: Erroneous initiation.
