TKT
geneOn this page
Summary
TKT (transketolase, HGNC:11834) is a protein-coding gene on chromosome 3p21.1, encoding Transketolase (P29401). Catalyzes the transfer of a two-carbon ketol group from a ketose donor to an aldose acceptor, via a covalent intermediate with the cofactor thiamine pyrophosphate. It is a selective cancer dependency (DepMap: 38.2% of cell lines).
This gene encodes a thiamine-dependent enzyme which plays a role in the channeling of excess sugar phosphates to glycolysis in the pentose phosphate pathway. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene.

Enriched among interaction partners
Reactome pathways and GO biological processes over-represented among this gene’s 136 IntAct physical interaction partners (hypergeometric vs the genome-wide background, BH-FDR, gene-set size 15–500, ranked by fold). A functional readout of the neighbourhood — distinct from this gene’s own memberships above, and biased toward well-studied / hub proteins, so read it as themes rather than proof.

Molecules with ChEMBL bioactivity
1 molecules (phase ≥1), by development phase (incl. off-target/promiscuous compounds). Patent mentions across the top 20 by phase: 1,538 (via chembl_molecule»patent_compound — counts attach to the compound, not the gene–compound relationship, so off-target/promiscuous molecules can dominate).

PubChem BioAssay actives
92 with measured affinity, of 118 total; 50 most potent distinct compounds. Largely complementary to BindingDB; screening values are coarse (µM, 4 dp), so sub-nM hits tie at the floor.
