 109-288 4.93e-97

P53 DNA-binding domain; P53 is a tumor suppressor gene product; mutations in p53 or lack of expression are found associated with a large fraction of all human cancers. P53 is activated by DNA damage and acts as a regulator of gene expression that ultimatively blocks progression through the cell cycle. P53 binds to DNA as a tetrameric transcription factor. In its inactive form, p53 is bound to the ring finger protein Mdm2, which promotes its ubiquitinylation and subsequent proteosomal degradation. Phosphorylation of p53 disrupts the Mdm2-p53 complex, while the stable and active p53 binds to regulatory regions of its target genes, such as the cyclin-kinase inhibitor p21, which complexes and inactivates cdk2 and other cyclin complexes.

 35-59 2.86e-11

Transactivation domain 2; This is a N-terminal transactivation domain (TAD) domain 2 found in p53 proteins. In p53 two TAD domains are found termed TAD1 (residues 1-39) and TAD2 (residues 40-61), both of which have been shown to be able to independently activate gene transcription and are intrinsically disordered protein domains that adopt a helical conformation for at least part of their length when bound. This inherent flexibility allows the TADs to adapt to and bind a broad range of proteins. This entry describes TAD2 which can independently interact with Taz2 domain of the histone acetyltransferase p300. It has also been shown to bind to OB-fold domain of replication protein 70 A (RPA) as well as the pleckstrin homology (PH) domain of the p62 and Tfb1 subunits of human and yeast TFIIH.
