生化/生理作用
膜联蛋白是普遍存在的同源蛋白，在钙存在的情况下结合磷脂。参与凋亡过程的细胞变化包括早期磷脂不对称的损失。这种现象是普遍存在的，不局限于刺激或哺乳动物细胞，也发生在昆虫和植物细胞中。在活细胞中，磷脂酰丝氨酸通过Mg2+ATP依赖酶氨磷脂转位酶传输至脂二层内部。发生细胞凋亡时，磷脂酰丝氨酸转运到细胞膜的外表面。磷脂酰丝氨酸从内膜表面到外膜表面的移动是细胞凋亡的早期指标，膜联蛋白V及其偶联物与磷脂酰丝氨酸相互作用且具有较强的特异性，可用于检测细胞凋亡。膜联蛋白V偶联物可用于检测明显早于基于DNA分析的凋亡细胞。 荧光染料标记的膜联蛋白V可应用于流式细胞术、荧光显微镜和激光扫描细胞术中。

Phosphatidlyserine (PS) exposure on the erythrocyte surface endows the cell with the propensity of adhering to vascular endothelium. Because individuals with sickle cell disease (SCD) manifest loss of erythrocyte membrane asymmetry with PS exposure, we have assessed the contribution of

Membranes from human placenta contain proteins which inhibit the activity of phospholipases A2 by binding to phospholipid thus impeding substrate availability. We used unilamellar mixed liposomes and a partially purified cytosolic phospholipase A2 from placenta for characterizing this substrate-depleting activity.

Helicobacter pylori colonizes half of the global population and causes gastritis, peptic ulcer disease or gastric cancer. In this study, we were interested in human annexin (ANX), which comprises a protein family with diverse and partly unknown physiological functions, but

Annexin V is a protein of unknown biological function that undergoes Ca(2+)-dependent binding to phospholipids located on the cytosolic face of the plasma membrane. Preliminary results presented herein suggest that a biological function of annexin V is the inhibition of
