| ----------- | --------------------------------------------------- | ---------------------------------------------------- | ----------------------------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------- |

| OPN1LW | Opsin 1, long-wave-sensitive (red cone opsin) | G-protein-coupled receptor (photopigment protein) | Cone photoreceptor cells in the retina (red cones) | Embedded in the disc membranes of the outer segment (plasma membrane of photoreceptor outer segment) |

| TAS2R38 | Taste receptor type 2 member 38 | G-protein-coupled receptor (taste receptor) | Taste receptor cells of the tongue (especially in taste buds of fungiform papillae) | Plasma membrane of taste receptor cells |

| CFTR | Cystic fibrosis transmembrane conductance regulator | Chloride ion channel (ABC transporter family) | Epithelial cells (airway, pancreas, intestine, sweat glands) | Plasma membrane (apical surface) |

| TYR | Tyrosinase | Enzyme (copper-containing oxidase) | Melanocytes (skin, hair follicles, eyes) | Melanosomes (specialized lysosome-related organelles) |

| FUT1 | Fucosyltransferase 1 | Glycosyltransferase (adds fucose to glycans) | Erythroid precursor cells (bone marrow red blood cell precursors) | Golgi apparatus (lumen) |

| ABO | ABO blood group glycosyltransferase | Glycosyltransferase (adds A/B antigens to H antigen) | Erythroid precursor cells (bone marrow red blood cell precursors) | Golgi apparatus (lumen) |

| HBB | Hemoglobin subunit beta | Globin (oxygen-binding protein) | Red blood cells (erythrocytes) | Cytoplasm (as part of hemoglobin tetramers, no organelles in mature RBCs) |
