    text
  • type II transmembrane proteins
  • is in the peripheral ER and does not enter the inner nuclear membrane (INM)
  • basic FUNCTION
  • TOR1AIP2 regulates the distribution and activity of TOR1A within the ER and NE lumen suggesting functional defects in the mutant protein responsible for DYT1 dystonia
  • endoplasmic reticulum membrane protein
  • TOR1AIP1, TOR1AIP2 regulate Torsin ATPase activity through an active site complementation mechanism
  • TOR1AIP2 is the most important component of the Torsin system with respect to viral production
  • oligomerizes likely to engage and transiently disassemble torsinA oligomers, and is thereby positioned to transduce cytoplasmic signals to the inner nuclear membrane (INM) through torsinA
  • might be an important molecule for maintaining genomic integrity and stability through upregulating or downregulating a cascade of genes to permit normal preimplantation embryo development

  • impaired interaction of torsinA with TOR1AIP2 and/or TOR1AIP1 may thus contribute to the development of dystonia
  • depending on redox status, an ATP hydrolysis mutant of torsinA interacts with lamina-associated polypeptide 1 (TOR1AIP1) and lumenal domain like LAP1 (TOR1AIP2)
  • LRRFIP2 and TOR1AIP2 are FATylation substrates
  • activity of TorsinA and the related ATPase TorsinB strictly depends on TOR1AIP1 and TOR1AIP2, that are integral parts of the Torsin/cofactor AAA ring, forming a composite, membrane-spanning assembly
  • TOR1AIP1 and TOR1AIP2, reversibly co-assemble with and activate torsin A (POMUID: 26092934)
