Description
技术领域
本发明属于基因工程技术领域,特别涉及一种基因重组高稳定性人胶原寡肽MYS-1及其制备方法与应用。
背景技术
胶原(Collagen)是动物机体中的一类结构蛋白,占人体总蛋白质含量的25%至35%。它是细胞外基质的主要成分,在维护细胞、组织、器官的正常生理功能以及修复损伤等方面发挥着重要作用。胶原具有极低的免疫原性、可降解性、生物相容性、生物吸收性、机械性、止血性、无毒性和细胞生长促进等功能,在医学临床、生物材料、生物医药、食品化工以及化妆品行业研究应用十分广泛。研究表明,胶原蛋白是调节皮肤水含量和PH值、调节黑色素形成及修复受损细胞的关键功能因子,可有效改善组织细胞微环境,进而令肌肤亮泽、光白、水嫩而富有活力。
胶原在生物体中的表达十分复杂,首先胶原蛋白基因在细胞核中转录;然后原胶原α链被共翻译运输到内质网腔中经过脯氨酸羟化酶、赖氨酸羟化酶、蛋白质酶修饰形成带有N端和C端的原胶原蛋白三螺旋,然后通过原胶原蛋白N端及C端蛋白酶作用将两端的肽链切除,胶原蛋白分子再规则地按四分之一错位相接,自组装成胶原蛋白微纤维,最后在赖氨酸氧化酶的作用下,共价交联形成胶原纤维。
已经研究表明表皮和真皮中的多种生物学过程可以由不同多肽调节,胶原作为一种大分子化合物,代谢时在体内被胶原酶切割解旋,再被系列蛋白酶裂解为小分子短肽而发挥其生物学功能,胶原水解多肽、寡肽可被用于医美产品及化妆品中,发挥其抗衰、美白等生物学功效,而对于其他大多数生物大分子或化合物而言,这种可及性不易实现。
目前,胶原蛋白生产主要有传统提取、化学合成及基因重组制备技术。传统提取技术通过水解天然胶原得到系列水解产物,但其免疫原性的应用风险难以避免;化学合成胶原蛋白的成本高;基因重组技术具有产率高、成本低、生产的蛋白、多肽或寡肽活性高、无病毒隐患等优势,使得基因重组小分子胶原多肽具有良好的产业化前景,特别是具有高稳定性的基因重组胶原寡肽,具有巨大的市场应用潜力。
