應用
肌酸激酶已被用作体外翻译测定中使用的翻译缓冲液的组分,并且作为能量再生混合物的组分。
生化/生理作用
肌酸激酶(CK)是一种胍基激酶,消耗ATP催化肌酸可逆磷酸化为磷酸肌酸。它在具有高能量需求的细胞中快速再生ATP中起着至关重要的作用。人血液中CK水平的增加表明神经系统和心肌疾病、恶性低温和某些肿瘤。金属(例如Mg、Mn和Ca)充当CK的辅助因子。它还形成蛋白激酶C的底物,蛋白激酶C是参与细胞生长的重要信号分子。人们发现 CK的酶促反应产物,磷酸肌酸,可以阻止 HIV(人类免疫缺陷病毒)在巨噬细胞中复制。

Much of the regulation of gene expression occurs at the level of protein synthesis. In addition to the canonical translation factors, a multitude of proteins and microRNAs (miRNAs) act as regulatory trans-acting factors. Mechanistic analysis of translational control benefits from

GdmCl-induced unfolding of rabbit muscle creatine kinase, CK, has been studied by a variety of physico-chemical methods including near and far UV CD, SEC, intrinsic fluorescence (intensity, anisotropy and lifetime) as well as intensity and lifetime of bound ANS fluorescence.

The crystal structure of rabbit muscle creatine kinase, solved at 2.35 A resolution by X-ray diffraction methods, clearly identified the active site with bound sulfates surrounded by a constellation of arginine residues. The putative binding site of creatine, which is

Spermatozoa are more efficient at supporting normal embryonic development than spermatids, their immature, immediate precursors. This suggests that the sperm acquires the ability to support embryonic development during spermiogenesis (spermatid to sperm maturation). Here, using Xenopus laevis as a model

For a long time, it has been assumed that the only role of sperm at fertilization is to introduce the male genome into the egg. Recently, ideas have emerged that the epigenetic state of the sperm nucleus could influence transcription
