用抗蛋白激酶C多克隆抗体在大鼠肝细胞核、核基质和核板层中鉴定出一对免疫反应带。这两种多肽在SDS-聚丙烯酰胺凝胶上显示出77和74 kDa的表观分子量,并且似乎是紧密结合的核组分,耐洗涤剂和高盐提取。考虑到编码蛋白激酶C的基因的复杂性,这两种形式的酶可能是特异性位于细胞核中的翻译产物,参与将生长因子和肿瘤启动子产生的调节信号转导到基因组装置。
A doublet of immunoreactive bands has been identified in rat liver nuclei, nuclear matrix and lamina by means of a polyclonal antibody against protein kinase C. The two polypeptides show an apparent molecular weight of 77 and 74 kDa on SDS-polyacrylamide gels, and appear to be tightly bound nuclear components, resistant to detergent and high salt extraction. Given the complexity of the genes encoding for protein kinase C, these two forms of the enzyme might be translational products specifically located in the nucleus, involved in the transduction to the genomic apparatus of regulatory signals generated by growth factors and tumor promoters.
