The list of taste receptors and chemosensors included in PlantMolecularTasteDB

Comments. 1) The initial indicates specia: h- human, f- fish, m- mouse, r- rat, gg- chicken, mg-turkey, tg- zebrafinch, xt-frog. 2) The user should keep in mind while performing a search on taste receptors or chemosensors that in cases of synonims, in general we mantained on each phytochemical entry the term/synonim used in the cited reference.
Bitter taste receptors:

• Human bitter taste receptors: hTAS2R- There are 25 human bitter receptors: hTAS2R1, hTAS2R3, hTAS2R4, hTAS2R5, hTAS2R7, hTAS2R8, hTAS2R9, hTAS2R13, hTAS2R14, hTAS2R16, hTAS2R19 (syn. hTAS2R23, hTAS2R48), hTAS2R20 (syn. hTAS2R49), hTAS2R30 (syn. hTAS2R47), hTAS2R31 (syn. hTAS2R44), hTAS2R38 (syn. hTAS2R61), hTAS2R39, hTAS2R40, hTAS2R41, hTAS2R42, hTAS2R43, hTAS2R45, hTAS2R46 (syn. hTAS2R54; hTAS2R75), hTAS2R48, hTAS2R50 (syn. hTAS2R67, hTAS2R51). Also, taking into account that five human TAS2Rs (hTAS2R19, 41, 42, 45 and 60) are still orphan receptors, they should not be included in the search.
• Mouse bitter taste receptors: mTAS2R – The mouse bitter taste receptors mentioned in PlantMolecularTasteDB are mTAS2R105, mTAS2R106, mTAS2R108, mTAS2R109, mTAS2R114, mTAS2R117, mTAS2R119, mTAS2R120, mTAS2R121, mTAS2R123, mTAS2R125, mTAS2R126, mTAS2R135, mTAS2R137, mTAS2R138, mTAS2R140, mTAS2R144, mTAS2R150
• Other bitter taste receptors: chickenTAS2R (ggTAS2R1, ggTAS2R2, ggTAS2R7); turkeyTAS2R (mgTAS2R3, mgTAS2R4) ; zebra finchTAS2R (tgTAS2R5, tgTAS2R6, tgTAS2R7); frogTAS2R (xtTAS2R11, xtTAS2R20, xtTAs2R29, xtTAS2R37, xtTAS2R5, xtTAS2R9a); lemurTAS2R16; pandaTAS2R20; felineTAS2R2, felineTAS2R46
