摘要：

乳脂球膜蛋白是乳腺在泌乳时包被在脂肪滴外的膜蛋白。乳脂肪球膜（milk fat globule membrane，MFGM）是磷脂、鞘脂和多种蛋白质组成的3层膜结构。乳脂球膜蛋白包含100余种蛋白质，含量最丰富的8种蛋白质为黏液素1、黄嘌呤氧化还原酶、黏液素15、CD36、嗜乳脂蛋白、乳凝集素、脂肪分化相关蛋白和脂肪酸结合蛋白。乳脂球膜蛋白已被证明具有丰富的开发利用价值，包括：反映奶牛母体的生理状态；作为幼体的营养和免疫来源，会影响犊牛的发育和母源抗体；会影响人和动物的免疫调节和体质，未来可能应用于疾病的治疗。作者介绍了乳脂球膜蛋白的来源、组成及一种新建立的乳脂球膜蛋白结构，阐述了几个主要蛋白的生理特性及乳脂球膜蛋白的研究进展，并对未来的研究方向提出建议。

Abstract:

Milk fat globule membrane protein is packaged outside the fat granule during mammary gland lactating. Milk fat globule membrane has three-layered structure composed of phospholipids,sphingolipids and proteins. Milk fat globule membrane protein contains more than one hundred kinds of proteins,of which there are the most abundant of eight kinds of proteins including mucin 1,xanthine oxidoreductase,mucin 15,CD36,butyrophilin,lactadherin,adipophilin,fatty acid binding protein .Milk fat globule membrane protein has been shown to have special value which reflects the physiological state of cow,affects the growth of calf and maternal immune as a source of nutrition and immunity for calves,and affects the human and animal's immunity regulation and physical fitness,it may be applied to treat diseases in the future. This article summaries the study of milk fat globule membrane protein in recent years aimed at describing the source,composition of the milk fat globule membrane proteins,introducing a novel established structure of milk fat globule membrane protein,explaining the physiological characteristics of some main proteins and progress in milk fat globule membrane proteins research and making recommendations for future research directions.

Key words: milk fat globules; milk fat globule membrane proteins; research progress
