Function
WHEP-TRS domains are helix-turn-helix domains. They are found in variable number in the glutamyl-prolyl tRNA synthetase(EPRS) proteins. They have an important function in protein–protein interactions between synthetases. WHEP domains exhibit high-affinity interactions with tRNA, indicating a putative evolutionary relationship to facilitate tRNA binding to fused synthetases, thereby enhancing catalytic efficiency.[1]
Protein interactions
EPRS is a component of the interferon-gamma-activated inhibitor of translation (GAIT) complex, which interacts with stem-loop elements (GAIT elements) in mRNAs encoding proinflammatory proteins, for example, vascular endothelial growth factor-A (VEGFA). WHEP domains interact with the GAIT element in the 3′UTR of target mRNAs and with the regulatory protein NS1-associated protein-1 (NSAP1).[1]
Structure
A conserved domain of 46 amino acids, called WHEP-TRS has been shown [2] to exist in a number of higher eukaryote aminoacyl-transfer RNA synthetases. This domain is present one to six times in several enzymes. There are three copies in mammalian aminoacyl-tRNA synthetase in a region that separates the N-terminal glutamyl-tRNA synthetase domain from the C-terminal prolyl-tRNA synthetase domain, and six copies in the intercatalytic region of the Drosophila enzyme. The domain is found at the N-terminal extremity of the mammalian tryptophanyl- tRNA synthetase and histidyl-tRNA synthetase, and the mammalian, insect, nematode and plant glycyl- tRNA synthetases.[3]

A conserved domain of 46 amino acids, called WHEP-TRS has been shown [ PUBMED:1756734 ] to exist in a number of higher eukaryote aminoacyl-transfer RNA synthetases. This domain is present one to six times in the several enzymes. There are three copies in mammalian multifunctional aminoacyl-tRNA synthetase in a region that separates the N-terminal glutamyl-tRNA synthetase domain from the C-terminal prolyl-tRNA synthetase domain, and six copies in the intercatalytic region of the Drosophila enzyme. The domain is found at the N-terminal extremity of the mammalian tryptophanyl-tRNA synthetase and histidyl-tRNA synthetase, and the mammalian, insect, nematode and plant glycyl-tRNA synthetases [ PUBMED:8463296 ]. The structure of a human WHEP-TRS domain has been solved and consists of two helices arranged in a helix-turn-helix [ PUBMED:11123902 ]. The WHEP-TRS domain may play a role in the association of tRNA-synthetases into multienzyme complexes [ PUBMED:9556618 ].

Pfam Clan
This family is a member of clan S15_NS1 (CL0600), which has the following description:
The clan contains the following 4 members:

We store a range of different sequence alignments for families. As well as the seed alignment from which the family is built, we provide the full alignment, generated by searching the sequence database (reference proteomes) using the family HMM. We also generate alignments using four representative proteomes (RP) sets and the UniProtKB sequence database. More...

We make a range of alignments for each Pfam-A family. You can see a description of each above. You can view these alignments in various ways but please note that some types of alignment are never generated while others may not be available for all families, most commonly because the alignments are too large to handle.

Structures
For those sequences which have a structure in the Protein DataBank, we use the mapping between UniProt, PDB and Pfam coordinate systems from the PDBe group, to allow us to map Pfam domains onto UniProt sequences and three-dimensional protein structures. The table below shows the structures on which the WHEP-TRS domain has been found. There are 25 instances of this domain found in the PDB. Note that there may be multiple copies of the domain in a single PDB structure, since many structures contain multiple copies of the same protein sequence.
