TLDR Neuronatin is found in specific cells within rat testis, hair follicles, tongue, and pancreas, suggesting it has various roles in tissue development and function.
The 2019 study investigated the localization of Neuronatin (NNAT) in rat tissues, finding it in various cell types across the testis, hair follicle, tongue, and pancreas. NNAT was present in epithelial basal cells of the tongue, spermatids and spermatozoa in the testis, insulin-positive and exocrine cells in the pancreas, taste receptor cells, and the inner root sheath of whisker hair follicles. The study highlighted NNAT's cell- or tissue-specific localization in the endoplasmic reticulum and its interaction with SERCA2, suggesting diverse roles in tissue development and cellular functions. However, the number of rats used in the study was not mentioned in the summary.
