The TP53 protein has three major functional domains: a transactivation domain at its N-terminal, a central DNA-binding domain (which includes mutation hotspots) and tetramerization and regulatory domains at the C-terminal.
In Kit, these regions include the juxtamembrane domain, which is purported to prevent kinase autoactivation in the absence of ligand binding [47], and the extracellular domain, which includes the SCF-binding site.
It is dominated by the globular head domain, which includes the sialic acid binding site 130 230 and a number of glycosylation sites, which have increased since 1918 [ 9].
The C-terminal portion of the receptor includes the ligand binding domain which recognizes specific hormones, vitamins, retinoids or other lipophilic compounds.
Similar genes are associated with the putative tetrachloroethene RDase gene of G. lovleyi strain SZ and a putative RDase gene of D. hafniense strain DCB2; however, the genes of the latter two bacteria include an FMN binding domain, which is absent in strain 2CP-C (Figure S4) [72].
Transcription factors can be made up of multiple protein domains, and these might include a DNA binding domain (which recognizes specific target DNA sequences) or a domain that interacts with the transcriptional machinery to regulate the expression of genes.
One example is the ZnF-UBP domain (zinc-finger ubiquitin binding domain), which is present at the N-terminal to the USP domain in several fly DUBs, including CG12082, CG4165, CG4166 (Nonstop, Not), and CG7288.
He added a DNA binding domain, which is slightly different than the native ecdysone domain.
The region in UTX corresponding to the JMJ13 C4HCHC domain is the zinc binding domain, which coordinates only one zinc ion (Fig. 4b 31.
The signature motifs of NRs are the DNA-binding domain (DBD), which includes a Cys-Cys zinc coordinating region, and the ligand-binding domain (LBD), a carboxy-terminal domain that binds ligands and facilitates receptor dimerization and coactivator recruitment.
