Ubiquitin regulatory domain X (UBX) found in UBX domain protein 11 (UBXN11) and similar proteins; UBXN11, also termed colorectal tumor-associated antigen COA-1, or socius, or UBX domain-containing protein 5 (UBXD5), belongs to the UBXD family of proteins that contains the ubiquitin regulatory domain X (UBX) with a beta-grasp ubiquitin-like fold, but without the C-terminal double glycine motif. UBX domain is typically located at the carboxyl terminus of proteins, and participates broadly in the regulation of protein degradation. UBXN11 may function as a cofactor of p97 (also known as VCP or Cdc48), which is a homohexameric AAA ATPase (ATPase associated with a variety of activities) involved in a variety of functions ranging from cell-cycle regulation to membrane fusion and protein degradation. UBXN11 also acts as a novel interacting partner of Rnd proteins (Rnd1, Rnd2, and Rnd3/RhoE), new members of Rho family of small GTPases. It directly binds to Rnd GTPases through its C-terminal region, and further participates in disassembly of actin stress fibers. UBXN11 also binds directly to Galpha12 and Galpha13 through its N-terminal region. As a novel activator of the Galpha12 family, UBXN11 promotes the Galpha12-induced RhoA activation.

Ubiquitin regulatory domain X (UBX) structurally similar to a beta-grasp ubiquitin-like fold; The UBXD family of proteins contains the ubiquitin regulatory domain X (UBX) with a beta-grasp ubiquitin-like fold, but without the C-terminal double glycine motif. UBX domain is typically located at the carboxyl terminus of proteins, and participates broadly in the regulation of protein degradation. Members in this family function as cofactors of p97 (also known as VCP or Cdc48), which is a homohexameric AAA ATPase (ATPase associated with a variety of activities) involved in a variety of functions ranging from cell-cycle regulation to membrane fusion and protein degradation. Based on domain composition, UBXD proteins can be divided into two main groups, with and without ubiquitin-associated (UBA) domain.

Ubiquitin regulatory domain X (UBX) 2 found in UBX domain protein 9 (UBXN9, UBXD9, or ASPSCR1) and similar proteins; UBXN9, also termed tether containing UBX domain for GLUT4 (TUG), or alveolar soft part sarcoma chromosomal region candidate gene 1 protein (ASPSCR1), or alveolar soft part sarcoma locus (ASPL), or renal papillary cell carcinoma protein 17 (RCC17), belongs to the UBXD family of proteins that contains two ubiquitin regulatory domains X (UBX) with a beta-grasp ubiquitin-like fold, but without the C-terminal double glycine motif. UBX domain is typically located at the carboxyl terminus of proteins, and participates broadly in the regulation of protein degradation. In addition, UBXN9 contains an N-terminal ubiquitin-like (Ubl) domain. UBXN9 functions as a cofactor of p97 (also known as VCP or Cdc48), which is a homohexameric AAA ATPase (ATPase associated with a variety of activities) involved in a variety of functions ranging from cell-cycle regulation to membrane fusion and protein degradation. However, high-affinity interacting protein ASPL efficiently promotes p97 hexamer disassembly, resulting in the formation of stable p97:ASPL heterotetramers; the extended UBX domain (eUBX) in ASPL is critical for p97 hexamer disassembly and facilitates the assembly of p97:ASPL heterotetramers.UBXN9 is involved in insulin-stimulated redistribution of the glucose transporter GLUT4, assembly of the Golgi apparatus. In addition to GLUT4, UBXN9 also controls vesicle translocation by interacting with insulin-regulated aminopeptidase (IRAP), a transmembrane aminopeptidase. UBXN9 and its budding yeast ortholog, Ubx4p, are multifunctional proteins that share some, but not all functions. Yeast Ubx4p is important for endoplasmic reticulum-associated protein degradation (ERAD) but UBXN9 appears not to share this function.
