Evidence for the dependence of UapA translocation to the PM on Sec24, Sec13, actin and SsoA tSNARE, as well as, for the need for actin polymerization in COPII formation, is described in the text. The role of actin for the hypothesized close-range transport and fusion of uncoated vesicles carrying UapA to the PM is highly speculative, as well as the existence of an ER-to-PM intermediate compartment. For details see main text.
