Gene Group (FlyBase)
UNCLASSIFIED GTPASES -
This group comprises GTPases that do not classify under other groups in FlyBase.
RECQ-LIKE DNA HELICASES -
The eukaryotic homologues of the Escherichia coli RecQ DNA helicase play conserved roles in the maintenance of genome stability, functioning during DNA replication and possibly in an S phase replication checkpoint. At least three of the human RecQ-like helicases are implicated in heritable diseases: BLM is mutated in Bloom's syndrome, WRN in Werner's syndrome, and RECQL4 in Rothmund-Thomson syndrome.

Model Confidence:
  • Very high (pLDDT > 90)
  • Confident (90 > pLDDT > 70)
  • Low (70 > pLDDT > 50)
  • Very low (pLDDT < 50)

AlphaFold produces a per-residue confidence score (pLDDT) between 0 and 100. Some regions with low pLDDT may be unstructured in isolation.

Testis-specificity index

Additional Descriptive Data

RecQ5 transcripts are detected throughout development on northern blots with the highest levels in ovaries and early embryos. Transcripts are found to be uniformly distributed in syncytial blastoderm embryos and localized to the periphery of the cellular blastoderm embryo by in situ hybridization. During oogenesis, RecQ5 transcripts are detectable mainly in nurse cells of stage 10 egg chambers and accumulate in the oocyte in stages 11 and 12.

      DNA damage caused by methyl-methanesulfonate (MMS) increases the level of RecQ5 in S2 cells. This overexpression perturbs cell-cycle progression under the condition of DNA damage.

      The RecQ5 protein is a ssDNA-stimulated ATPase and an ATP-dependent DNA helicase. It is also a ssDNA-dependent GTPase, and GTP binding stimulates the ATP-dependent DNA helicase activity of the protein.

      RecQ5 expression is developmentally regulated and the DNA helicase activity of RecQ5 might be involved in the DNA metabolism of early embryos.

      Isolated a cDNA clone, homologous to E.coli recQ, from a D.melanogaster library.
