    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

    The testis specificity index was calculated from modENCODE tissue expression data by Vedelek et al., 2018 to indicate the degree of testis enrichment compared to other tissues. Scores range from -2.52 (underrepresented) to 5.2 (very high testis bias).

    Reference
    Additional Descriptive Data

    spaw transcripts are detected at low levels in primary spermatocytes and are barely detected in early elongation spermatids. Robust signals are detected in more elongated spermatids at the distal ends. Transcripts localize into a ball shape at the ends of spermatids bundles, trailing away proximally to a less abundant, speckled distribution (called a comet pattern).

          Additional comments

          One or more of the processed transcripts for this gene contain(s) two non-overlapping open reading frames (ORFs). The non-overlapping ORFs are represented by hubl and spaw.

          Source for merge of CG30365 BcDNA:AT04457 was shared cDNA (AT04457) ( date:030529 ).

          Source for identity of: spaw CG30365

          Nomenclature comments
          Etymology

          The gene is named "spacewatch", based on the "comet"-like pattern of expression of the transcript in spermatid bundles; the mRNA localises into a ball shape at the end of the spermatid bundle, trailing away proximally to a less abundant, speckled distribution.
