Coiled-coil domain-containing protein 85B

Gene

CCDC85B

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Functions as a transcriptional repressor. May inhibit the activity of CTNNB1 in a TP53-dependent manner and thus regulate cell growth. May function in adipocyte differentiation, negatively regulating mitotic clonal expansion.2 Publications

Miscellaneous

May be the cellular homolog of HDAG. Overexpression inhibited HDV replication, whereas overexpression of HDAG reversed the inhibition, suggesting that HDAG may assist HDV replication by forming a complex with DIPA.
