RNA-binding protein that binds specific mRNAs including the ASH1 mRNA, coding for a repressor of the HO endonuclease. Part of the mRNA localization machinery that restricts accumulation of certain proteins to the bud and in the daughter cell. Recruits the MYO4-SHE3 complex to the ASH1 mRNA. Recruits also LOC1 and PUF6 to ASH1 mRNA, which are required for translational repression of this mRNA (By similarity). Homodimer and homotetramer. Interacts with LOC1, MYO4, PUF6, SHE3 and with RNA pol II subunits RPO21, SPT4 and SPT5. Shuttles between the nucleus and cytoplasm and is exported in an mRNA-dependent manner. The presence in the nucleus is essential for PUF6 and LOC1 to bind the ASH1 mRNA. Belongs to the SHE2 family.
