The density regulated protein (DENR) forms a stable heterodimer with malignant T-cell-amplified sequence 1 (MCT-1) which interacts with the 40S ribosomal subunit during initiation, reinitiation and recycling stages, playing a role in regulation of non-canonical translation initiation and ribosomal recycling [1]. This entry represents the N-terminal domain of DENR, containing a zinc ion-binding site, which preserves the structure of DENR's MCT-1-binding interface that is essential for the dimerization [1-3]. DENR likely coordinates the Zn ion mainly via three rather than four cysteines [3].
This Pre-PUA-like domain is found in a wide variety of proteins including Swiss:Q61211. the eukaryotic translation initiation factor 2D, where it is found at the N-terminus.

The PUA domain named after Pseudouridine synthase and Archaeosine transglycosylase, was detected in archaeal and eukaryotic pseudouridine synthases, archaeal archaeosine synthases, a family of predicted ATPases that may be involved in RNA modification, a family of predicted archaeal and bacterial rRNA methylases. Additionally, the PUA domain was detected in a family of eukaryotic proteins that also contain a domain homologous to the translation initiation factor eIF1/SUI1; these proteins may comprise a novel type of translation factors. Unexpectedly, the PUA domain was detected also in bacterial and yeast glutamate kinases; this is compatible with the demonstrated role of these enzymes in the regulation of the expression of other genes [1]. It is predicted that the PUA domain is an RNA binding domain.
