DHX30 Knockout Cell Line (HEK293)

The choice depends on whether you are studying DHX30's role as a mitochondrial DEAH-box RNA helicase or modeling DHX30-associated neurodevelopmental disorder. The Knockout line is the standard tool for asking whether DHX30 is required for these processes — DHX30 is a DEAH-box helicase principally localized to mitochondrial RNA granules where it participates in mitoribosome assembly and mitochondrial RNA processing; DHX30 also has roles in cytoplasmic stress granule formation and translation regulation. Overexpression is useful for studying DHX30 in heterologous expression contexts. For mitochondrial RNA biology research, the EDITGENE DHX30 Knockout in HEK293 enables study of DHX30 biology. DHX30 heterozygous missense mutations in the helicase motifs cause autosomal dominant intellectual disability with severe motor impairment and absent speech (NEDMIAS, DHX30-related neurodevelopmental disorder). Rescue with wild-type or patient-derived DHX30 mutants enables disease genotype-function studies. The knockout is valuable for studying mitochondrial RNA processing and emerging DHX30-related neurodevelopmental disorder mechanisms.

Primary applications: • Mitochondrial RNA granule biology: mitochondrial RNA granule imaging and composition analysis in DHX30-null cells. • Mitoribosome assembly: 39S/55S mitoribosome sucrose gradient analysis given DHX30's role in mitoribosome biogenesis. • NEDMIAS modeling: rescue with patient-derived missense mutations in DHX30 helicase motifs for genotype-function studies of intellectual disability syndrome. • Mitochondrial respiratory chain: OXPHOS complex assembly and activity analysis. EDITGENE recommends this model for researchers investigating mitochondrial RNA biology and DHX30-related neurodevelopmental disorder mechanisms.

Yes. DHX30 rescue experiments require attention to mitochondrial targeting and helicase architecture: • Construct design: use a codon-modified DHX30 sequence with a small C-terminal tag (FLAG, HA). DHX30 has N-terminal mitochondrial targeting sequence and DEAH-box helicase core — preserve mitochondrial localization. • Mitochondrial localization validation: confirm mitochondrial localization by appropriate compartment markers. • NEDMIAS mutation rescue: patient-derived missense mutations in helicase motifs enable disease genotype-function studies. • ATPase-dead rescue: Walker A motif mutations abolish ATPase activity. • Functional readout: rescue should restore mitoribosome assembly and mitochondrial RNA processing. HEK293 transduces efficiently with lentivirus and supports stable rescue line generation.
