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).

Transcript Expression
in situ
Stage
Tissue/Position (including subcellular localization)
Reference
Additional Descriptive Data

Pgam2 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).

        Other Comments

        Comparison of the gene structure of Pglym78 and Pglym87 suggests that Pglym87 arose through retrotransposition from a Pglym78 transcript, additional more complex mechanisms may have played some role in the origin of Pglym87. Structural properties suggest Pglym87 is a pseudogene with a peculiar rate and pattern of evolution, aspects of Pglym87 molecular evolution suggest it might be a functional gene having puzzling aspects in its structure.

        Source for merge of: Pglym87 CG17645

        Additional comments

        The Pglym87 gene may have been derived from the Pglym78 gene by retroposition.

        Nomenclature History

        Source for identity of: Pgam2 Pglym87

        Nomenclature comments

        Renamed from 'Pglym87' to 'Pgam2' to (i) remove the species-specific reference to cytogenetic location; (ii) use the more widely used nomenclature prefix for this gene across species.
