    601 amino acids
    Molecular mass:
    63853 Da
    Quaternary structure:
    • Binds signal sequences of proteins that are targeted to the endoplasmic reticulum. Interacts (via UBA domain) with GJA1 (not ubiquitinated) and with ubiquitin; both compete for the same binding site (By similarity). Homodimer. Interacts (via UBA domain) with ubiquitin and with polyubiquitin chains. Interacts (via ubiquitin-like domain) with PSMD4, a regulatory subunit of the 26S proteasome. Interacts with ATXN1/SCA1. Interaction with ATXN1 inhibits polyubiquitination of UBQLN4 and interferes with PSMD4 binding.
    • Sequence=AAF19084.1; Type=Erroneous initiation; Note=Translation N-terminally shortened.; Evidence={ECO:0000305}; Sequence=AAH06410.1; Type=Erroneous initiation; Note=Translation N-terminally extended.; Evidence={ECO:0000305};
