Synthesized phosho peptide around human TIF1β (Ser824)

This antibody detects endogenous levels of Human TIF1β (phospho-Ser824).The name of modified sites may be influenced by many factors, such as species (the modified site was not originally found in human samples) and the change of protein sequence (the previous protein sequence is incomplete, and the protein sequence may be prolonged with the development of protein sequencing technology). When naming, we will use the "numbers" in historical reference to keep the sites consistent with the reports. The antibody binds to the following modification sequence (lowercase letters are modification sites):LSsQE

The protein encoded by this gene mediates transcriptional control by interaction with the Kruppel-associated box repression domain found in many transcription factors. The protein localizes to the nucleus and is thought to associate with specific chromatin regions. The protein is a member of the tripartite motif family. This tripartite motif includes three zinc-binding domains , a RING , a B-box type 1 and a B-box type 2 , and a coiled-coil region. [provided by RefSeq , Jul 2008] ,

Domain: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. ,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. ,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. ,PTM:Phosphorylated upon DNA damage , probably by ATM or ATR. ,similarity:Belongs to the TRIM/RBCC family. ,similarity:Contains 1 bromo domain. ,similarity:Contains 1 PHD-type zinc finger. ,similarity:Contains 1 RING-type zinc finger. ,similarity:Contains 2 B box-type zinc fingers. ,subcellular location:Associated with centromeric heterochromatin during cell differentiation through CBX1. ,subunit: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. ,
