乳铁蛋白基因(LTF)编码乳铁蛋白,这是一种多功能糖蛋白,属于转铁蛋白家族。乳铁蛋白主要存在于乳汁、唾液、泪液等分泌液中,具有铁离子结合能力,参与铁的转运和代谢。其生物学功能包括抗菌、抗病毒、免疫调节和抗氧化等。乳铁蛋白通过结合铁离子限制病原微生物的生长,还能直接破坏细菌细胞膜,抑制病毒吸附宿主细胞。在免疫调节方面,它能激活巨噬细胞和中性粒细胞,增强先天免疫反应。LTF基因的突变可能导致乳铁蛋白功能异常,与多种疾病相关,如慢性炎症、自身免疫疾病和某些癌症。LTF过表达可能增强机体抗感染能力,但过度铁螯合可能导致缺铁性贫血;降低表达则可能增加感染风险并影响铁代谢。LTF属于转铁蛋白家族,该家族成员均具有铁结合能力,参与铁稳态维持。乳铁蛋白在婴儿营养、免疫防御和炎症调控中发挥关键作用,其表达水平变化与多种病理过程密切相关。
This gene is a member of the transferrin family of genes and its protein product is found in the secondary granules of neutrophils. The protein is a major iron-binding protein in milk and body secretions with an antimicrobial activity, making it an important component of the non-specific immune system. The protein demonstrates a broad spectrum of properties, including regulation of iron homeostasis, host defense against a broad range of microbial infections, anti-inflammatory activity, regulation of cellular growth and differentiation and protection against cancer development and metastasis. Antimicrobial, antiviral, antifungal and antiparasitic activity has been found for this protein and its peptides. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2014]
此基因是转基因家族的成员,并且其蛋白质产物在嗜中性粒细胞的次级颗粒中发现。蛋白质是主要的铁结合在牛奶和身体分泌物的蛋白质具有抗微生物活性,从而使其成为非特异性免疫系统的重要组成部分。蛋白质展示属性的广谱,包括铁稳态的调节,宿主防御广泛微生物感染,抗炎活性,细胞生长和分化和防止癌症发展和转移的调节。抗微生物,抗病毒,抗真菌和抗寄生虫活性,已经发现这种蛋白质和其肽。另外剪接转录变体ENCoding不同的亚型已经发现了这种基因。 [由RefSeq的,2014年9月提供]
