Gene Summary
zucchini (zuc) encodes a member of the phospholipase D superfamily. It is anchored in the outer mitochondrial membrane and functions in the processing of primary piRNA transcripts through its endonuclease activity. zuc depletion causes sterility, transposon de-repression and accumulation of piRNA cluster transcripts.

Gene Group (FlyBase)
UNCLASSIFIED PHOSPHORIC DIESTER HYDROLASES -

This group comprises endoribonucleases that do not classify under other groups in FlyBase.
Protein Function (UniProtKB)
Cardiolipin hydrolase present at the mitochondrial outer membrane required for piRNA metabolic process. Acts by catalyzing the hydrolysis of cardiolipin (diphosphatidylglycerol) to form phosphatidate (phosphatidic acid or PA) at the mitochondrial outer membrane surface, promoting the piRNA metabolic process. Plays a key role in primary biogenesis of piRNAs and is required during oogenesis to repress transposable elements and prevent their mobilization. piRNAs mediate the repression of transposable elements during meiosis by forming complexes composed of piRNAs and Piwi proteins and govern the methylation and subsequent repression of transposons. Involved in trans-silencing effect (TSE), a homology-dependent repression mechanism by which a P-transgene inserted in subtelomeric heterochromatin via its role in piRNA biogenesis.
(UniProt, Q9VKD7)
Summary (Interactive Fly)

nuclease that functions in germline RNAi processes, required in dorso-ventral patterning pathway - required early during oogenesis for the translational silencing of osk mRNA and at later stages for proper expression of the Grk protein - regulates telomere-specific transposable elements

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.

Subunit Structure (UniProtKB)

Homodimer (By similarity). Interacts with miga/CG12125 (PubMed:26711011).

(UniProt, Q9VKD7)
Domain

In contrast to other members of the phospholipase D family, contains only one PLD phosphodiesterase domain, suggesting that it has a single half-catalytic and requires homodimerization to form a complete active site.
