these findings suggest that Tip60-ATM signaling has a functional contribution to the recruitment of TMPK to DNA damage sites, thereby increasing local dTTP synthesis for DNA repair.
Title: Thymidylate kinase is critical for DNA repair via ATM-dependent Tip60 complex formation.
The RAMD simulations on product-bound structures of both ttTMPK and hTMPK, revealed that while several exit patterns of the products are permissible, the sequential exit mode is the most preferred pattern for both ttTMPK and hTMPK enzymes. Additionally, the product release from the hTMPK was found to be faster and more directional as compared to ttTMPK

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
