Comprehensive analysis process for iOR

Sequence, Structures, and Functions

Sequence

iOR genes possess multiple exons, and a large number of pseudogenes are produced in insect genomes because of the rapid evolution of the iOR protein family (Robertson, 2019; Legan et al., 2021). In iORbase v1.0 (Lee et al., 2023), we proposed a method for screening gene annotation results using structural integrity.

Structure

Functional iORs can be distinguished from pseudogenes based on the 7 transmembrane segments and anchor domains. Moreover, the release of protein structure predictive methods like alphafold (Abramson et al., 2024) has enabled the prediction of 3D structures for iORs, which aids in understanding their functional roles.

Function

The interaction relationship between iOR and different odor molecules is called the function of iOR, and the decoding process of iOR function is called deorphanization. The deorphanization of a growing number of iORs is still challenging given the difficulties associated with conducting insect physiological and biochemical experiments.

iORbase v2.0 Released

We are excited to announce the release of iORbase 2.0 with enhanced features and expanded database.

Due to technical reasons, iorbasev1.0 is temporarily unavailable and will be relaunched later (most of the functions of v1.0 have been covered by v2.0).
