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.

Comment: weak

(Barreau et al., 2008)
Additional Descriptive Data

c-cup 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 in shallow cup-like shapes at the ends of spermatids bundles (called a cup pattern).

            c-cup transcripts accumulate in cup-shaped structures also at the distal tips of elongating spermatids.

            Origin and Etymology
            Discoverer
            Etymology

            The gene is named "calcutta-cup", based on the "cup"-like pattern of expression of the transcript in spermatid bundles; the mRNA localises in shallow cup-like shapes at the end of the spermatid bundles.
