UBA-like domain found in yeast UBX domain-containing protein 1 (Ubx1) and similar proteins
Ubx1, also called suppressor of high-copy PP1 protein (Shp1), is the substrate-recruiting cofactor of AAA-adenosine triphosphatase Cdc48 in Saccharomyces cerevisiae. In concert with ubiquitin-like Atg8, Cdc48 and Ubx1 are involved in the regulation of autophagosome biogenesis. Ubx1 also functions as a regulator of phosphoprotein phosphatase 1 (PP1) with differential effects on glycogen metabolism, meiotic differentiation, and mitotic cell cycle progression. All family members contain an N-terminal ubiquitin-associated (UBA)-like domain.
