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.

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

        dsRNA made from templates generated with primers directed against this gene is tested in an RNAi screen for effects on actin-based lamella formation.

        capt functions specifically to limit actin-filament formation catalysed by ena protein at apical cell junctions in the follicular epithelium.

        Mutant show altered F-actin and oocyte polarity during oogenesis.

        capt organises the polarised distribution of F-actin and mRNAs during oogenesis.

        capt is required to prevent excessive polymerisation of actin filaments in the eye disc. It is also required for cells to change shape in the morphogenetic furrow and prevents premature neuronal differentiation in the eye disc.

        capt is required for cells to constrict apically in the morphogenetic furrow in the eye disc and is also required to prevent premature neuronal differentiation.

        Identification: identified as a mutation that affects both the actin cytoskeleton and oocyte polarity in female germline clones.

        capt helps control the global distribution of actin filaments in cells.

        Loss of capt function in clones results in the dramatic re-organisation of actin filaments in many tissues, leading to the loss of some actin structures and the accumulation of massive clumps of F-actin at characteristic ectopic sites.

        The autosomal "FLP-DFS" technique (using the P{ovoD1-18} P{FRT(whs)} P{hsFLP} chromosomes) has been used to identify the specific maternal effect phenotype for the zygotic lethal mutation. capt is required for germ cell viability or early oogenesis.
