Abstract

The invention discloses gene cloning of goat Ran binding protein 9 (RanBP9) and a positioning detection method of the goat RanBP9 in sperm and relates to the technical field of biology. The method includes the steps of firstly, designing cloning primers; secondly, performing RT-PCR amplification on a sequence, and sequencing to obtain a goat RanBP9 gene sequence; thirdly, analyzing the relative expression quantity of RanBP9 mRNA; fourthly, expressing the RanBP9 in tissue; fifthly, using a sperm cell immunofluorescence method to detect the positioning of the RanBP9 in the sperm. The method has the advantages that the goat RanBP9 gene sequence is obtained, expression of the RanBP9 RNA and the RanBP9 in different tissue and positioning of the RanBP9 in the sperm are researched, and a foundation is laid for researching the functions of the RanBP9 in the growth of goat.

Description

technical field [0001] The invention discloses goat Ran-binding protein 9 (RanBP9) gene cloning and its location detection method in sperm, and relates to the field of biotechnology. Background technique [0002] RanBP9 can develop on its own in embryonic stem cells, and has an important regulatory role in the process of sperm and oogenesis. It is also a scaffold protein composed of multiple parts, and plays a role in mediating cell surface receptor proteins and intracellular signal transmission. important function. The function of RanBP9 protein is related to various biological processes, such as cell proliferation and apoptosis, growth and development of gonads, etc. In addition, RanBP9 is essential for mouse spermatogenesis and oogenesis, and there is a significant decline of RanBP9 in the development of testis mutants during the sperm cell reproduction stage. It is also a novel binding protein of neuroreceptor, which acts as an interactor in the cytoplasm to induce sig...
