Protein attributes

Sequence length	676 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Evidence at protein level.

General annotation (Comments)

Function	May play a role in cell death control. Acts as a transcriptional repressor. Has been shown to repress transcription of SRF in vitro and so may play a role in heart development. Ref.1
Subunit structure	Interacts with XIAP By similarity.
Subcellular location	Nucleus. Note: Some staining in the cytosol. Ref.1 Ref.5
Tissue specificity	In the embryo, widely expressed with highest levels in brain. In the adult, highest expression is found in the heart. Ref.1
Domain	The C-terminal region mediates transcriptional repression. Ref.1
Sequence similarities	Belongs to the TCF25 family.
