  1. 01LabIn vitro (cells)Mechanism

    In cytoplasm-depleted A431 cells, no thymosin beta‑4 variant or fragment passed the intact nuclear pore, so all were excluded from the nucleus.

    In plain wordsIn cells, none of the thymosin beta‑4 variants or fragments crossed the nuclear pore of cytoplasm-depleted cells.

    Summary
    In contrast to Oregon Green cadaverine, none of the variants or fragments of thymosin beta(4) could pass the intact nuclear pore of cytoplasm-depleted cells and were hence excluded from the nucleus.

    The localization of Oregon Green cadaverine-labeled thymosin beta(4), its fragments, and variants was investigated in cytoplasm-depleted A431 cells and in microinjected cells without and with fixation.

  3. 03LabIn vitro (cells)Mechanism

    In A431 cells, nuclear localization of thymosin beta‑4 did not depend on its actin-binding ability or its basic lysine cluster.

    In plain wordsIn cells, thymosin beta‑4 reached the nucleus without needing its actin-binding site or its lysine cluster.
