一般描述
蜡状芽孢杆菌的磷脂酰肌醇特异性磷脂酶 C (PI-PLC) 是一种 298 残基蛋白。属于一类普遍存在的酶。PI-PLC 具有单一的球状结构域,折叠成八(βα)桶板,其中只有 6 个 βα 单元在管中发现,链 IV 和 V 与 V 和 VI 之间缺少螺旋。
应用
蜡状芽孢杆菌的磷脂酰肌醇特异性磷脂酶 C 已被用于从细胞膜上切割绿色荧光蛋白-糖基磷脂酰肌醇 (GFP-GPI) 的 GPI 锚定蛋白。 它也被用于侵袭实验,以测试 PLAP 是否参与了克氏锥虫对人类 2 类型上皮细胞 (HEp-2) 的侵袭。
生化/生理作用
用于释放锚定的 GPI 膜中的蛋白质。
外形
含有磷酸盐缓冲盐、EDTA 和稳定剂
分析说明
根据 Ellman 等人 的研究测定乙酰胆碱酯酶。
其他说明
在 30°C、pH 7.4 条件下,每分钟释放 1 个单位的乙酰胆碱酯酶。

The development of tissues and organs requires close interaction of cells. To achieve this, cells express adhesion proteins such as the neural cell adhesion molecule (NCAM) or its Drosophila ortholog Fasciclin 2 (Fas2). Both are members of the Ig-domain superfamily

Microglia are resident immune cells in the central nervous system, showing a regular distribution. Advancing microscopy and image processing techniques have contributed to elucidating microglia's morphology, dynamics, and distribution. However, the mechanism underlying the regular distribution of microglia remains to
