General annotation (Comments)

Function

Forms a complex with a KRAB-domain transcription factor and increases the efficiency of KRAB-mediated repression. Silences transcription through an interaction with HP1 proteins. Acts as a corepressor of transcription for the KRAB zinc finger proteins and as a moderator of the repression activity. May play a role as a coactivator for CEBPB and NR3C1 in the transcriptional activation of the Alpha-1-acid glycoprotein gene By similarity.

Subunit structure

Associated with HP1 alpha (CBX5), beta (CBX1) and gamma (CBX3) in interphase nuclei By similarity. Interacts with ZNF382; enhances ZNF382 transcriptional repressor activity By similarity. Interacts with CEBPB and NR3C1 By similarity. Interacts with NCOR1 and CHD3. Interacts with SETDB1, ZFP53 and ZFP68. Interacts directly with CBX5 via the PxVxL motif.

Subcellular location

Nucleus By similarity. Note: Associated with centromeric heterochromatin during cell differentiation through CBX1 By similarity.

Domain

The HP1 box is both necessary and sufficient for HP1 binding. The RING finger domain and the B-box domains mediate interaction with CEBPB. The PHD domain enhances the CEBPB transcriptional activity By similarity.

Contains one Pro-Xaa-Val-Xaa-Leu (PxVxL) motif, which is required for interaction with chromoshadow domains. This motif requires additional residues -7, -6, +4 and +5 of the central Val which contact the chromoshadow domain.

Post-translational modification

Phosphorylated upon DNA damage, probably by ATM or ATR. Ref.13 Ref.14 Ref.15 Ref.16 Ref.17 Ref.18 Ref.19 Ref.20 Ref.21

Sequence similarities

Belongs to the TRIM/RBCC family.

Contains 2 B box-type zinc fingers.

Contains 1 bromo domain.

Contains 1 PHD-type zinc finger.

Contains 1 RING-type zinc finger.

Binary interactions
