About TK1

Cytogenetic location: 17q25.3 Genomic coordinates (GRCh38): 17:78,174,079-78,187,204 (from NCBI)

This gene has 6 transcripts (splice variants) and 209 orthologues. Broad expression in bone marrow (RPKM 21.7), lymph node (RPKM 12.6) and 18 other tissues.

Summary

The protein encoded by this gene is a cytosolic Enzyme that catalyzes the addition of a gamma-phosphate group to thymidine. This creates dTMP and is the first step in the biosynthesis of dTTP, which is one component required for DNA replication. The encoded protein, whose levels fluctuate depending on the cell cycle stage, can act as a low activity dimer or a high activity tetramer. High levels of this protein have been used as a biomarker for diagnosing and categorizing many types of cancers. [provided by RefSeq, Oct 2016]
