Biological Activity for iHAP1

iHAP1 is an allosteric activator of protein phosphatase 2A (PP2A) (EC₅₀ ~ 0.12 μM); activates PP2A-B56ε subunit. Inhibits proliferation of lymphoblastic leukemia (T-ALL) cell lines including KOPT-Ki, SUPT-13 and RPMI-8402 (IC₅₀ values are 0.3 - 0.8 μM). Inhibits tubulin polymerization in vitro (IC₅₀ = 0.87 μM). Blocks cell cycle causing prometaphase arrest in vitro. Inhibits T-ALL tumor growth in a transgenic zebrafish model and a mouse T-ALL xenograft model.
