STAT5 (STAT5A, STAT5B)

Short target page →

STAT5 is the messenger that carries growth signals from FLT3, JAK2 and BCR::ABL1 into the nucleus and switches on survival genes in leukaemia cells. No drug hits STAT5 directly yet; the FLT3 and ABL inhibitors work by cutting off the signal above it. This dossier gathers the 0 products (0 approved), 0 trials, 0 pathways and 0 resistance routes in the corpus that involve it, with external identifiers so it can be joined to UniProt, ChEMBL, Open Targets and the rest of biology.

Biology

The JAK-STAT pathway record lists STAT5 as the STAT of leukaemias, alongside STAT3 as the hub of IL-6-driven survival. Constitutive STAT5 signalling is the readout of FLT3, JAK2, MPL and BCR::ABL1 activity in the corpus mechanism steps, and no direct STAT5 inhibitor is recorded.

Where it is found
  • FLT3-mutant AML (downstream of FLT3-ITD/TKD)
  • Ph-positive CML and ALL (downstream of BCR::ABL1)
  • Myeloproliferative neoplasms (downstream of JAK2 and MPL)
