Abstract
Муцини – це структурні компоненти епітеліального шару мукози, які захищають респіраторний, травний та репродуктивний тракти від негативних впливів зовнішнього оточення (мікроорганізмів, токсинів та хімічних або механічних подразників). Муцини складають групу високо молекулярних (> 200 кДа), полідисперсних та сильноглікозійованих білків, що знаходяться на поверхні більшості епітеліальних тканин. За останнє десятиріччя прогрес в розумінні структури та функцій муцинів, в основному, пов'язаний з одержанням кДНК клонів, кодуючих сімейство епітеліальних муцинів. На сьогодні це сімейство охоплює вісім муцинових генів (MUC1–MUC8) і очікується відкриття нових. Базуючись на первинній структурі та вивченні внутрішньоклітинної локалізації, епітеліальні муцини можна поділити на два класи: мембран-асоційовані (MUC1) та секреторні (MUC2–MUC8). Цей огляд сфокусовано на сучасних уявленнях про структуру продуктів муцинових генів та їхні функції в нормальних тканинах і при патологіях. Обговорюються також регуляція експресії муцинових генів, посттрансляційні модифікації та зміни в секреції і процссингу.
