Abstract

Because of low contents in the native organs and failure of the expression in cultured cells, the chromophore configurations of the pigments in Go-coupled opsin and peropsin groups in the opsin family are unknown. Here we have succeeded in expression of the amphioxus homologs of these groups in HEK293s cells and found that they can be regenerated with 11-cis- and all-trans-retinals, respectively. Light isomerized the chromophores of these opsins into the all-trans and 11-cis forms, respectively. The results strongly suggest that the physiological function of peropsin would be a retinal photoisomerase, while 11-cis configuration is necessary for the Go-coupled opsin groups.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
