Nuclear localization sequence ( NLS ) is the specific amino acid sequence on the signaling proteins to be sufficient for their nuclear translocation. 核定位序列(NLS)(NLS)是信号蛋白分子上与入核转运相关的氨基酸序列。
Nuclear transcription factors of NF κ B are inhibited by I κ B proteins, which inactivate NF κ B by trapping and masking the nuclear localization sequence of it in the cell cytoplasm. NFκB是一种重要的转录因子蛋白。由于其核定位信号序列被IκB所结合而限定在细胞质中。
Bioinformatics analysis showed no known nuclear localization signals inside the sequence of sAC. 生物信息学的分析没有在该基因内部发现已知的核定位序列(NLS)。
