摘要: F-box富含亮氨酸重复蛋白3基因(F-box and leucine rich repeat protein 3,FBXL3)能编码含F-box结构域的蛋白,属于F-box蛋白家族成员,在细胞核中发挥功能。F-box富含亮氨酸重复蛋白21基因(F-box and leucine rich repeat protein 21,FBXL21)位于细胞质中,其功能与FBXL3基因功能存在拮抗作用。FBXL3与FBXL21蛋白在哺乳动物体内产生分子昼夜节律的负反馈循环中均都起重要作用。FBXL3通过形成SCF(SKP1-CUL1-F-box)复合物行使E3泛素连接酶功能,并通过泛素化促进隐花色素(Cryptochrome,CRY)蛋白的降解参与生物钟调控,FBXL21通过泛素化使CRY蛋白积累参与生物钟调控,两者对于CRY蛋白的拮抗作用能够稳定哺乳动物生物钟。本文首先介绍了生物节律以及生物钟分子的组成,然后综述了FBXL家族基因在昼夜节律循环中的调控作用及其突变后对季节性发情性状的影响,有助于后续探索FBXL家族基因突变后影响绵羊季节性发情性状的具体分子机制,为利用现代生物技术改变绵羊发情的季节性提供新思路。

Abstract: The F-box and leucine rich repeat protein 3 (FBXL3) gene encodes the protein containing the F-box domain. It belongs to the F-box protein family and plays a role in the nucleus.The F-box and leucine rich repeat protein 21 (FBXL21) is located in the cytoplasm, and its function is antagonistic to the function of FBXL3 gene. FBXL3 and FBXL21 proteins both play important roles in the negative feedback cycle of molecular circadian rhythm in mammals. FBXL3 participates in the regulation of biological clock by forming SCF complex, which exercise E3 ubiquitin ligase function and promote the degradation of CRY protein through ubiquitination. FBXL21 makes CRY protein accumulation to participate in biological clock regulation through ubiquitination. The antagonism of FBXL3 and FBXL21 to CRY protein can stabilize the biological clock of mammals. In this review, the biological rhythm and the elements of biological clock were introduced firstly. Then, the regulation mechanism of FBXL family in circadian rhythm and the effects of FBXL family mutation on seasonal estrus traits in sheep were reviewed. It is helpful to explore the molecular mechanism of FBXL family mutation affecting sheep seasonal estrus deeply, and provide new ideas for changing sheep estrous season using modern biotechnology.

Key words: biological rhythm, FBXL3 gene, FBXL21 gene, seasonal estrus, molecular mechanism, sheep
