    Gene Snapshot
    javelin (jv) encodes an actin associated protein with roles in actin organization during bristle growth. [Date last reviewed: 2019-03-07]
    Protein Function (UniProtKB)
    Important for normal assembly of actin bundles during bristle formation.
    (UniProt, M9NE38)
    Phenotypic Description (Red Book; Lindsley and Zimm 1992)
    jv: javelin
    All bristles and hairs cylindrical, instead of tapered, with small enlargement before tip. Cell autonomous and useful as a marker for epidermal clones (Morata and Ripoll, 1975, Dev. Biol. 42: 211-21). RK2.

    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.

                Other Comments

                New annotation (CG32397) in release 3 of the genome annotation.

                Definitive denticle belt phenotypes (abnormal hairs and/or bristles) are foreshadowed by abnormal organisation of the actin cytoskeleton in embryonic epidermal cells.

                Mutant alleles are useful as markers in clonal analysis.
