Biological Activity for Epiblastin A

Epiblastin A is a CK1 inhibitor (IC₅₀ values are 0.8, 3.7 and 3.8 μM for CK1δ, CK1ε and CK1α). Converts late-stage epiblast stem cells into germline-competent embryonic SC-like cells. Promotes activation and maintenance of the pluripotency network. Promotes ESC self-renewal at a concentration of 2 μM.
