9.B.422.1.1









Transmembrane protein TMEM26 of 368 aas and possibly 9 or 12 TMSs in a possible 3 + 3 + 3 or (less likely) 3 + 3 + 3 + 3 TMS arrangement. Members of this family play roles in beige adipocyte formation in overweight animals (Rachid et al. 2018), and may target obesity by influencing fat oxidation and thermogenesis (Liu et al. 2019). Its gene expression is influenced by emodin (Cheng et al. 2021) and activated by flavan-3-ols (Ishii et al. 2021).

9.B.422.1.4









TMEM26 of 505 aas and 4 C-terminal TMSs, which is where there is sequence similarity with other members of the family.  Clonorchis sinensis (family Opisthorchiidae) is an important foodborne parasite that has a major socioeconomic impact on ~35 million people predominantly in China, Vietnam, Korea and the Russian Far East. In humans, infection with C. sinensis causes clonorchiasis, a complex hepatobiliary disease that can induce cholangiocarcinoma, a malignant cancer of the bile ducts (Wang et al. 2018).
