In one study, a yeast two-hybrid screen using the C-terminal tail of the mouse melanocortin 4 receptor (MC4‐R) identified a positive clone exhibiting 63% amino acid identity with the C-terminal region of the mouse attractin gene product. This attractin‐like protein (ALP) directly interacts with MC4‐R—specifically between residues 303–313 on MC4‐R and residues 1280–1317 on ALP—and is co‐expressed in brain areas that are key regulators of energy balance."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": "Dissecting the genetics of the attractin system further, another study characterized both loss‐ and gain‐of‐function mutations in the related genes Atrn and Atrnl1. While mice lacking Atrn displayed multiple phenotypic abnormalities including neurodegeneration, reduced adiposity, and pigmentation changes, over‐expression of Atrnl1 was able to compensate for some of these deficits, indicating functional redundancy between these attractin family members in regulating neural integrity and metabolic processes."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "2"}]}, {"type": "t", "text": "Notably, neither abstract mentions or provides any evidence regarding the function of TTTY5.
