为了寻找可能由过氧化体增殖物(PPAR)激活的核受体的内源性配体,利用重组小鼠PPAR-α建立了一种固相结合分析方法,该方法包含一个MyC表位、一个组氨酸重复序列和一个激酶A结构域。用~(32)P-γ-α体外标记后,评价了纯化的~(32)P-PPAR-ATPr与一组固定在硅胶层上的不同天然和合成脂质的结合情况。二氧化硅层的放射自显影显示与两类主要的亲脂化合物结合。第一类是(多)不饱和脂肪酸。属于第二类的化合物的特征是存在总的正电荷,如长链胺、狮身人面罩(鞘氨醇)和溶糖鞘糖脂(神经氨酸)。PPAR-α不与N-酰化的狮身人面像碱基(神经酰胺)或在初级羟基上磷酸化的鞘氨醇(鞘氨醇-1-磷酸)结合。考虑到PPAR-α和鞘磷脂在各种细胞过程中的作用,PPAR-α与狮身人面像碱基的结合可能是有意义的。
In a search for possible endogenous ligands of nuclear receptors that are activated by peroxisome proliferators (PPARs), a solid phase binding assay was developed employing recombinant mouse PPAR-α, containing a myc-epitope, a histidine repeat and a kinase A domain. After in vitro labelling with32P-γ-ATP, the binding of purified32P-PPAR-α to a panel of different natural and synthetic lipids, immobilized on silica layers, was evaluated. Autoradiographs of the silica layers revealed binding to two main classes of lipophilic compounds. A first class comprised (poly)unsaturated fatty acids. Compounds belonging to a second class were characterized by the presence of an overall positive charge such as long chain amines, sphingoid bases (sphingenine), and lysoglycosphingolipids (psychosine). PPAR-α did not bind to N-acylated sphingoid bases (ceramides) or to sphingenine phosphorylated at the primary hydroxy group (sphingenine-1-phosphate). The binding of PPAR-α to sphingoid bases might be of interest given the role of PPAR-α and sphingolipids in various cellular processes.
