|Synonyms||RNF82, TIF1, TIF1A|
|Function||Transcriptional coactivator that interacts with numerous nuclear receptors and coactivators and modulates the transcription of target genes. Interacts with chromatin depending on histone H3 modifications, having the highest affinity for histone H3 that is both unmodified at 'Lys-4' (H3K4me0) and acetylated at 'Lys-23' (H3K23ac). Has E3 protein-ubiquitin ligase activity. Promotes ubiquitination and proteasomal degradation of p53/TP53. Plays a role in the regulation of cell proliferation and apoptosis, at least in part via its effects on p53/TP53 levels. Up-regulates ligand-dependent transcription activation by AR, GCR/NR3C1, thyroid hormone receptor (TR) and ESR1. Modulates transcription activation by retinoic acid (RA) receptors, including RARA. Plays a role in regulating retinoic acid-dependent proliferation of hepatocytes (By similarity).|
|Cellular Location||Nucleus. Cytoplasm. Note=Colocalizes with sites of active transcription. Detected both in nucleus and cytoplasm in some breast cancer samples. Predominantly nuclear|

TIF1 Alpha/TRIM24 is a member of a family of proteins that control transcription and chromatin remodeling through their interaction with transcription factors. The family of TIF1s (transcriptional intermediary factor 1) includes TIF1-alpha, TIF1-beta, and TIF1-gamma. TIF1-alpha plays an important role in development and mediates transcriptional control by interacting with the AF2 region of nuclear receptors such as estrogen, retinoic acid, and vitamin D3 receptors. TIF1-alpha has been shown to be a repressor of transcription. This transcriptional repression involves histone deacetylation and interaction with members of the heterochromatin protein 1 family.
