CYCLOPHILINS -
Cyclophilins are a class of evolutionary conserved peptidyl prolyl cis/trans isomerases. In vertebrates, they form binary complexes with their ligand, cyclosporine A, and are involved in key biochemical processes including protein folding, receptor signalling, protein trafficking, and transcription. Cyclophilins are characterized by the presence of a 'Cyclophilin-type peptidyl-prolyl cis-trans isomerase domain' (IPR002130). (Adapted from PMID:25986569.)

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).

        An alternative splice form of Moca-cyp mRNA, clone "3H44", results in the splitting of the long Moca-cyp open reading frame into two smaller potential open reading frames - "ORF1" (144 amino acids) and "ORF2" (685 amino acids). The first 131 residues of "ORF1" are identical to the first 131 amino acids of the long Moca-cyp protein, and "ORF2"is identical to the C-terminal tail of the long Moca-cyp protein.
