与神经丝相关的蛋白激酶活性(cAMP,cGMP,Ca2+非依赖性)几乎完全被0.8 M KCl提取。通过蔗糖梯度超离心或磷酸纤维素层析分离两种活性。其中之一磷酸化特异性神经丝蛋白,并优先的三联体(200 kDa,145 kDa和68 kDa),但既不酪蛋白也不IIA型组蛋白。第二种活性被鉴定为酪蛋白激酶I,并且不催化神经丝蛋白的磷酸化。
Protein kinase activities associated with neurofilament (cAMP, cGMP, Ca2+-independent) were almost completely extracted by 0.8 M KCl. Two activities were separated by either sucrose gradient ultracentrifugation of phosphocellulose chromatography. One of them phosphorylates specifically neurofilament proteins and preferentially the triplet (200 kDA, 145 kDa and 68 kDa) but neither casein nor type IIAhistone. The second activity was identified as casein kinase I and does not catalyze the phosphorylation of neurofilament protein.
