主要碱性蛋白（英語：Major basic protein，MBP），全称为嗜酸性粒细胞主要碱性蛋白（英語：Eosinophil Major basic protein），也称为蛋白多糖2（Proteoglycan 2，PRG2），是一种由人类基因PRG2编码的蛋白质^[5]。

MBP在结构上类似于凝集素（糖结合蛋白），特别是与C-型凝集素在折叠上相似。但与C-型凝集素不同（C-型凝集素在钙的存在下会结合各种碳水化合物），MBP既不与钙结合也不与这些糖类结合，而是识别並結合硫酸乙酰肝素（heparan sulfate）。MBP的两种晶体结构已被测定。^[6]^[7]

相互作用

主要碱性蛋白已知可与妊娠相关血浆蛋白A发生蛋白質交互作用。^[8]^[9]^[10]
