Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Mtrex often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
- rRNA-processing arch domain
- DEAD/DEAH box helicase
- helicase superfamily c-terminal domain
- ATP binding
- enzyme
- DSHCT (NUC185) domain
- protein binding
- Helicase conserved C-terminal domain
- RNA helicase
- 6-pyruvoyl-tetrahydropterin synthase related domain (membrane protein)
- N-terminal helicase domain of the DEAD-box helicase superfamily
- DEAD-like helicases superfamily
- P-loop containing Nucleoside Triphosphate Hydrolases
