Usp36 is essential for cell and organism viability because of its role in ribosomal RNA processing and protein synthesis, which is mediated, at least in part, by regulating DHX33 stability.
Title: Loss of the deubiquitinase USP36 destabilizes the RNA helicase DHX33 and causes preimplantation lethality in mice.
DHX33 doublet is due to alternative translation initiation by two in-frame initiation codons. DHX33 translation initiation from either AUG codon happens at equal efficiency. Short DHX33 protein has similar cellular location and functions with full-length DHX33. Leaky scanning normally occurs in DHX33 mRNA translation, which may serve as a safeguard mechanism to ensure optimal DHX33 translation efficiency.
Title: Alternative translation initiation from two in-frame start codons in DHX33 gene.
results directly implicate DHX33 as a crucial player in establishing rRNA synthesis rates in the face of Ras(V12) or ARF signals, adjusting ribosome biogenesis to match the appropriate growth or antigrowth signals
Title: P19ARF and RasV¹² offer opposing regulation of DHX33 translation to dictate tumor cell fate.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
