The protein Ycf1p is a member of a large superfamily of membrane proteins found in all organisms. By utilizing the energy of ATP, known as the energy currency of the cell, these proteins actively transport solutes into and out of the cell, regulate the function of other proteins, or open pores or channels to allow charged species to pass through. These ATP-using membrane proteins have a conserved molecular architecture that contains two regions embedded in the cellular envelope (known as the membrane) and two regions located inside the cell (known as the cytoplasm). Proper regulation of this process is essential, as many genetic diseases, including cystic fibrosis and adrenoleukodystrophy, result from dysfunction of different proteins in this ubiquitous superfamily.

蛋白质YCF1P是在所有生物体中发现的大型膜蛋白的大型超家族的成员。通过利用ATP的能量（称为细胞的能源货币），这些蛋白质会主动将溶质传输到细胞中，调节其他蛋白质的功能，或者开放的孔或通道允许带电的物种通过。这些使用ATP的膜蛋白具有保守的分子结构，其中包含两个嵌入细胞包膜中的区域（称为膜）和位于细胞内部的两个区域（称为细胞质）。适当调节这一过程是必不可少的，因为许多遗传疾病，包括囊性纤维化和肾上腺素肌营养不良，这是由于这种无处不在的超家族中不同蛋白质功能障碍引起的。
