The nuclear matrix isolated from rat liver nuclei whose protein sulfhydryl groups were oxidised with the o-phenantroline-copper (OP-Cu) complex was enriched with a set of 32-44 kd polypeptides identified as core proteins of ribonucleoprotein particles (RNP). The most conspicuous protein in the nuclear matrix was a 36 kd protein present as a disulfide-linked homodimer. The propensity of protein 36 to be oxidised and form intermolecular associations suggests that it may contribute to the interaction of RNP particles with the nuclear matrix and thus to their spatial distribution in the nucleus.
从大鼠肝细胞核中分离得到的核基质，其蛋白质巯基用邻菲罗啉 - 铜（OP-Cu）复合物氧化后，富含一组32 - 44kd的多肽，这些多肽被鉴定为核糖核蛋白颗粒（RNP）的核心蛋白。核基质中最显著的蛋白质是一种36kd的蛋白质，它以二硫键连接的同二聚体形式存在。蛋白质36易于被氧化并形成分子间缔合，这表明它可能有助于RNP颗粒与核基质的相互作用，从而有助于它们在细胞核中的空间分布。
