There are two major functional domains, the N-terminal domain (NT), contains the major receptor binding region, the C-terminal domain (CT), contains the lipid binding region, which is also thought to bind Aβ [9], [10].
Experimental studies on apoE are focused on its receptor binding region, which is located between residues 130 150 and is critical for its biological activity.
The signal molecule binding region, which is located in the N-terminal portion of the protein and a helix-turn-helix motif (HTH) located in the C-terminal, which is responsible for the protein binding to the target promoters [13] [15].
It consists of an extracellular ligand binding region, which is connected to the cytosolic region through a hydrophobic transmembrane domain.
Interestingly, A. niger P43 has GST C-terminal domain at the N-terminal of the tRNA binding region, which is different from the human counterpart.
The mutations of these residues within the Mdm2/MdmX binding region, which are normally phosphorylated downstream of DNA damage, result in constitutive p53 activation.
Immediately adjacent to the N-terminal J-domain of Class I J-proteins is a glycine/phenylalanine (GF -rich linker reGF -richlinker by the client pregion binding region, which is composed ofollowedrrel topology domains, CTD1 and CTD2.
The p. K23N (c.69 G->T) mutation in the HSF4 gene detected in our present study was located within the highly conserved HSF DNA binding region, which is shared across heat shock transcription factors (HSFs) and between species, as shown by multiple-sequence alignment.
Amino acids 30 59 of YopK were identified as a RACK1-binding region, which was further analyzed by introducing pair-wise alanine substitutions covering aa 26 52 (indicated in Figure 1A) in the truncated aa 7 59 form of the protein by use of a two-step PCR strategy and synthetic oligonucleotides, as previously described [64].
This generated ~5000 p300 binding regions which are associated with active enhancers.
