For the scallop eye transcriptomes, 49.16 (A. irradians) to 54.97 (P. magellanicus) from the sequences were annotated with protein domains. On typical, 2.five protein domains have been annotated per sequence for a total of three,463 and 38,778 annotated protein domains for a. irradians and P.PLOS One ��-Tocotrienol Epigenetic Reader Domain particular | www.plosone.orgLightMediated Function of Scallop EyeFigure 4.

In the sequences annotated by InterProScan, about 38 had no preceding blastx annotation, representing 19.12 from the A. irradians dataset and 20.24 with the P. magellanicus transcriptome. One of the most abundant protein domain annotations in each transcriptomes have been transmembrane regions (present in 35.81of the annotated sequences from A. irradians, and in 34.09 of the P. magellanicus annotated sequences) and signal peptides (42.17 and 39.84 in the annotated sequences within a. irradians and P. magellanicus datasets, respectively; Table four). Two added protein domain categories were examined: Gprotein coupled receptors (GPCRs), due to their prevalance in sensory systems, andTable three.

A very smaller proportion of annotated sequences had been GPCRs in every scallop eye dataset (0.four and 0.3 inside a. irradians and P. magellanicus, respectively). A single sequence was annotated as “opsin” in each and every scallop eye transcriptome, although the remaining annotated GPCRs had been identified as “Family A” GPCRs or simply “Gprotein receptors.” Transcription factors, however, created up a larger proportion on the InterProScan annotated sequences. Seven sorts of transcription variables were identified in P. magellanicus (paired box, homeodomain, winged helix, zinc finger, helixturnhelix, bzip, and srflike), although the A. irradians dataset only contained representatives from thre.
