Description of Recombinant Human TSGA10 Protein, N-His

Introduction to Recombinant Human TSGA10 Protein

Recombinant Human TSGA10 Protein, also known as testis-specific gene A10, is a protein that is encoded by the TSGA10 gene. This protein is primarily expressed in the testis and has been found to play a crucial role in male fertility and sperm function. It is a highly conserved protein, with homologs found in various species including humans, mice, and rats.

Structure of Recombinant Human TSGA10 Protein

The recombinant form of TSGA10 protein is produced by cloning and expressing the TSGA10 gene in a suitable host organism, such as E. coli or Chinese hamster ovary (CHO) cells. The resulting protein is a 32 kDa polypeptide consisting of 287 amino acids. It has a predicted isoelectric point of 5.6 and a high content of hydrophobic amino acids, suggesting a potential role in membrane interactions.

The crystal structure of TSGA10 protein has been determined, revealing a unique fold consisting of four α-helices and a β-sheet. This structure is highly conserved among different species, indicating its functional importance. The protein also contains a conserved domain, known as the TSGA10 domain, which is essential for its interaction with other proteins.

Activity of Recombinant Human TSGA10 Protein

Studies have shown that TSGA10 protein is involved in various cellular processes, including sperm maturation, capacitation, and fertilization. It is primarily expressed in the testis, where it is localized to the sperm tail, suggesting a role in sperm motility. TSGA10 has also been found to interact with other proteins involved in sperm function, such as SPAG1 and SPAG6.

Furthermore, TSGA10 protein has been shown to play a role in the acrosome reaction, a crucial step in fertilization where the sperm releases enzymes to penetrate the egg. It has been proposed that TSGA10 may regulate the fusion of the sperm plasma membrane with the outer acrosomal membrane, a process necessary for the acrosome reaction to occur.

Application of Recombinant Human TSGA10 Protein

Recombinant Human TSGA10 Protein has various potential applications in the field of reproductive biology and medicine. Due to its role in sperm function, it has been suggested as a potential biomarker for male infertility. Studies have shown that TSGA10 protein levels are significantly decreased in infertile men compared to fertile men, making it a potential diagnostic tool for male infertility.

In addition, TSGA10 protein has been proposed as a potential target for male contraception. By targeting this protein, it may be possible to inhibit sperm function without affecting testosterone levels, making it a safer alternative to current methods of male contraception.

Furthermore, recombinant TSGA10 protein has been used in research to study its role in sperm function. It has been used to investigate the interaction between TSGA10 and other sperm proteins, as well as its role in the acrosome reaction and fertilization. The availability of recombinant TSGA10 protein has greatly aided in understanding the function and mechanism of this protein in male fertility.

Conclusion

In summary, Recombinant Human TSGA10 Protein is a highly conserved protein primarily expressed in the testis. It plays a crucial role in sperm function and has potential applications in the diagnosis and treatment of male infertility. The availability of recombinant TSGA10 protein has greatly aided in understanding the structure and function of this protein, and further research on its role in male fertility is ongoing.
