Introduction to Recombinant Human TENT4A/PAPD7/TRF4 Protein
Recombinant Human TENT4A/PAPD7/TRF4 Protein, also known as Terminal Nucleotidyltransferase 4A, Poly(A) Polymerase Delta 7, or Telomerase Repeated Amplification 4, is a protein that plays a crucial role in the maintenance of telomere length and telomerase activity. This protein is encoded by the TENT4A gene and is a member of the poly(A) polymerase family. Recombinant Human TENT4A/PAPD7/TRF4 Protein is produced through recombinant DNA technology, making it a highly pure and bioactive protein that can be used in various research and diagnostic applications.
Structure of Recombinant Human TENT4A/PAPD7/TRF4 Protein
Recombinant Human TENT4A/PAPD7/TRF4 Protein is a 65 kDa protein composed of 585 amino acids. It contains a conserved catalytic domain in the C-terminal region, which is responsible for its poly(A) polymerase activity. This domain is essential for the addition of adenine nucleotides to the 3′ end of RNA molecules, which is crucial for telomere maintenance and regulation of telomerase activity.
In addition to the catalytic domain, Recombinant Human TENT4A/PAPD7/TRF4 Protein also contains a N-terminal domain, which is responsible for its interaction with other proteins involved in telomere maintenance. This domain is crucial for the formation of a functional telomerase complex and the regulation of telomerase activity.
Activity of Recombinant Human TENT4A/PAPD7/TRF4 Protein
Recombinant Human TENT4A/PAPD7/TRF4 Protein is a key component of the telomerase complex, which is responsible for the addition of telomeric repeats to the ends of chromosomes. This process is essential for the maintenance of telomere length, which is crucial for cell proliferation and survival. Recombinant Human TENT4A/PAPD7/TRF4 Protein acts as a poly(A) polymerase, adding adenine nucleotides to the 3′ end of RNA molecules, which are then used as a template for the synthesis of telomeric repeats by the reverse transcriptase subunit of telomerase.
In addition to its role in telomere maintenance, Recombinant Human TENT4A/PAPD7/TRF4 Protein has been shown to play a role in other cellular processes, such as mRNA decay and RNA quality control. It has been suggested that this protein may also have a role in the regulation of gene expression, although further research is needed to fully understand its function in these processes.
Application of Recombinant Human TENT4A/PAPD7/TRF4 Protein
Recombinant Human TENT4A/PAPD7/TRF4 Protein has a wide range of applications in both research and diagnostic settings. Its role in telomere maintenance and telomerase activity makes it a valuable tool for studying aging, cancer, and other diseases associated with telomere dysfunction. Recombinant Human TENT4A/PAPD7/TRF4 Protein can be used to study the mechanisms of telomere elongation and regulation of telomerase activity, as well as to screen for potential telomerase inhibitors or activators.
In addition, Recombinant Human TENT4A/PAPD7/TRF4 Protein can be used in diagnostic tests for telomere-related diseases. Its ability to accurately measure telomerase activity in patient samples makes it a valuable tool for the early detection and monitoring of diseases such as cancer and certain genetic disorders.
