Gene Summary
Dynamin related protein 1 (Drp1) encodes a dynamin-like GTPase that mediates mitochondrial fission through a process that involves translocation to the mitochondrial outer membrane and oligomerization. It is required for normal neuronal development and maintenance of postmitotic neuronal function and viability. [Date last reviewed: 2018-09-27] (FlyBase Gene Snapshot)

Gene Group (FlyBase)
DYNAMIN-LIKE GTPASES -
The Dynamin-like GTPases are a family of GTPases that undergo nucleotide-dependent dimerization and dimer-dependent GTP hydrolysis. They are implicated in membrane remodelling and endocytic membrane fission events. (Adapted from PMID:22233676).
Summary (Interactive Fly)

a Dynamin GTPase - regulates mitochondrial fission in normal cells including primary spermatocytes - mediates mitochondrial fragmentation during programmed cell death

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.

      Drp1 is required for the normal distribution of mitochondria in spermatocytes and the normal unfurling of the mitochondrial derivatives in early spermatids during sperm formation.

      Drp1 is required for normal mitochondrial distribution and morphology in all cells tested.

      Mutants show a defect in the formation and recruitment of the synaptic vesicle reserve pool.

      Drp1 is required for the proper cellular distribution of mitochondria.

      dsRNA directed against this gene causes defects in cytokinesis when tested in an RNAi screen in S2 cells.

      Required at the neuromuscular junction.

      Mutants show a distinct temperature sensitive paralysis phenotype.

      dsRNA made from templates generated with primers directed against this gene tested in RNAi screen for effects on Kc167 and S2R+ cell morphology.
