MBL2(甘露糖结合凝集素2)基因位于人类第10号染色体上,属于胶原凝集素(collectin)基因家族。该基因编码甘露糖结合凝集素(MBL),这是一种由肝脏合成的C型凝集素,在先天免疫系统中发挥重要作用。MBL的主要功能是通过识别病原体表面的糖结构(如甘露糖、N-乙酰葡糖胺等)来启动补体系统的凝集素途径,从而促进病原体的清除。MBL以寡聚体形式存在,其结构包含胶原样区域和碳水化合物识别区域,能够与多种微生物表面的糖类结合。MBL2基因存在多个多态性位点,特别是启动子区和外显子1的突变(如密码子52、54和57的突变)会导致MBL蛋白结构改变或表达水平降低,从而影响其功能。MBL缺乏与多种感染性疾病(如儿童反复感染、严重呼吸道感染)和自身免疫性疾病(如系统性红斑狼疮、类风湿关节炎)的风险增加相关。MBL2过表达可能增强对病原体的清除能力,但过高的MBL水平也可能与某些炎症性疾病相关;而MBL表达降低则会导致补体激活能力减弱,增加感染风险。在胶原凝集素家族中,MBL与其他成员(如SP-A、SP-D)共享类似的结构特征和免疫功能,均含有胶原样区域和凝集素区域,能够识别病原体相关分子模式并参与免疫防御。该基因家族成员在先天免疫、炎症调节和组织稳态中发挥重要作用。

中文English

该基因编码可溶性甘露糖结合凝集素或在血清中发现的甘露糖结合蛋白。编码的蛋白质属于聚集家族并且是先天免疫系统的重要元素。该蛋白质可识别的许多微生物甘露糖和N-乙酰氨基葡糖,和能够激活经典补体途径的。这个基因的缺陷已与易感性自身免疫性和感染性疾病相关联。 [由RefSeq的,2008年7月提供]
