部分折叠的mhcⅠ类α链与钙蛋白结合,直到β2-微球蛋白结合。
Partly folded MHC class Iα chains binds to calnexin until β2-microglobulin binds |
MHC class Iα:β-m complex is released from calnexin,binds a complex of chaperone proteins (calreticulin ERp57)and binds to TAP via
MHCⅠ类 α:β-m复合物从钙蛋白释放,结合了伴侣蛋白复合物(钙网蛋白ERp 57),并通过木薯素结合 (百度翻译)。 |
胞浆蛋白和核糖体缺陷产物(DISPS)是由蛋白酶体降解的多肽片段。TAP向ER传递肽
cytosolic proteins and defective ribosomal products(DRiPs)are degraded topetide fragements by the proteasome. TAP delivers peptides to the ER |
Apeptide binds the MHC class I molecule and completes its folding. The MHC class I molecule is released from the TAP complex and exported to the cell membrane
肽结合MHCⅠ类分子并完成折叠。MHCⅠ类分子从TAP复合物中释放出来并出口到细胞膜。
