SLC8A1基因(溶质载体家族8成员1,英文全称Solute Carrier Family 8 Member 1)属于SLC8基因家族,该家族编码钠钙交换体(NCX,英文全称Na+/Ca2+ exchanger),主要负责调节细胞内钙离子浓度。SLC8A1编码的蛋白称为NCX1,是一种跨膜蛋白,主要分布在心脏、肾脏和大脑等组织中,通过将3个钠离子转入细胞同时将1个钙离子转出细胞来维持钙离子稳态(钙离子稳态指细胞内钙离子浓度的平衡状态)。NCX1在心脏中尤为重要,参与心肌细胞的兴奋-收缩耦联(指电信号转化为机械收缩的过程),影响心跳节律和收缩力。SLC8A1基因突变可能导致NCX1功能异常,与多种疾病相关,如心律失常、心力衰竭和高血压。某些突变会降低NCX1的活性,导致细胞内钙离子超载(钙离子过多),引发心肌细胞损伤或异常电活动;而另一些突变可能增强NCX1功能,影响钙信号传导。SLC8A1过表达可能加剧钙离子外排,导致细胞内钙不足,影响肌肉收缩和神经信号传递;而表达降低则可能引发钙离子蓄积,增加氧化应激(指有害自由基积累导致的细胞损伤)和细胞凋亡(程序性细胞死亡)。SLC8A1还与神经系统疾病如癫痫和神经退行性疾病有关,因为钙信号紊乱会影响神经元功能。SLC8基因家族的共性是其成员均编码钠钙交换体,参与钙离子转运,但不同亚型(如NCX1、NCX2、NCX3)的组织分布和调控特性略有差异。例如,NCX2和NCX3主要在中枢神经系统表达,而NCX1在心脏中占主导。该家族蛋白均依赖钠离子梯度驱动钙离子转运,对维持细胞内环境稳定至关重要。研究还发现SLC8A1与药物反应相关,如地高辛(一种治疗心衰的药物)可能通过影响NCX1活性发挥作用。此外,SLC8A1的表达受激素(如甲状腺激素)和病理条件(如缺血缺氧)调控,其异常表达可能进一步影响其他钙相关基因(如SERCA2,肌浆网钙泵)的功能,形成连锁反应。

In cardiac myocytes, Ca(2+) concentrations alternate between high levels during contraction and low levels during relaxation. The increase in Ca(2+) concentration during contraction is primarily due to release of Ca(2+) from intracellular stores. However, some Ca(2+) also enters the cell through the sarcolemma (plasma membrane). During relaxation, Ca(2+) is sequestered within the intracellular stores. To prevent overloading of intracellular stores, the Ca(2+) that entered across the sarcolemma must be extruded from the cell. The Na(+)-Ca(2+) exchanger is the primary mechanism by which the Ca(2+) is extruded from the cell during relaxation. In the heart, the exchanger may play a key role in digitalis action. The exchanger is the dominant mechanism in returning the cardiac myocyte to its resting state following excitation.[supplied by OMIM, Apr 2004]

在心肌细胞,钙离子在舒张收缩浓度下,在高层次和低水平之间交替。收缩过程中的Ca(2+)浓度的增加主要是由于来自细胞内储存释放的Ca(2+)的。然而,一些钙离子也通过肌膜(质膜)进入细胞。期间放松,钙离子是细胞内的商店内隔离。为了防止细胞内储存的超载,钙(2+),该输入横跨肌膜必须从细胞挤出。的钠(+) - 钙离子交换体是通过该钙离子从细胞松弛期间挤出的主要机制。在心脏,交换器可能在洋地黄行动的??一个关键的角色。换热器是主要的机制在心肌细胞返回到其静止状态下的激励。[由OMIM 2004年四月供应]
