[C.elegansII] NMK. Cyclophilin family, transspliced to SL1. Partial sequence identity 83% to human CYP gene, 74% to yeast CSBY. Possible signal peptide. YAC Y14B8[WS, TP]
cyn-1 encodes a functional cyclophilin that is predicted to be secreted; cyn-1 expression increases as worms progress from the L1 larval stage to the adult stage; cyn-1 shares an operon with vha-13 and thus might be a previously undescribed V-ATPase component or ancillary protein.
Predicted to enable cyclosporin A binding activity and peptidyl-prolyl cis-trans isomerase activity. Predicted to be involved in protein folding. Located in mitochondrion. Human ortholog(s) of this gene implicated in several diseases, including Bell's palsy; aggressive periodontitis; and gastrointestinal system cancer (multiple). Is an ortholog of human PPIA (peptidylprolyl isomerase A); PPIAL4C (peptidylprolyl isomerase A like 4C); and PPIF (peptidylprolyl isomerase F).
[Page AM] Isolated independently by M. Hengartner and A. P. Page, Hengartner on library screening, and from mixed stage cDNA by A. P. Page using SL1, and known 3' seq from CEMSW74f.
[Page AM] No cosmids have been identified (there is a gap in this region). This places this gene in the centre of chromosome V.
[Page AM] Is transpliced by SL-1
Partial sequence identity 83% to human CYP gene, 74% to yeast CSBY. Possible signal peptide.
PPIase or cyclophilin, EC 5.2.1.8
This gene has been renamed with approval of the CGC (cyp-1->cyn-1)
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
