    text
  • ATP8A2 associated with TMEM30A localizes to the Golgi compartment
    • basic FUNCTION
  • transports phosphatidylserine and phosphatidylethanolamine from one side of a bilayer to another
  • implicated in the generation and maintenance of phosphatidylserine asymmetry in photoreceptor disc membranes
  • co-expression of ATP8A2 with TMEM30A results in the formation of properly folded heteromeric complex that is transported from the ER and to the Golgi compartment
    • CELLULAR PROCESS cell life, proliferation/growth
    PHYSIOLOGICAL PROCESS active transport
    text small molecule transport, negative control of cell proliferation
    PATHWAY
    metabolism
    signaling
    a component
  • functional ATP8A2-TMEM30A complex (N-linked glycosylation of TMEM30A plays an important role in the formation of a stable ATP8A2-CDC50A protein complex)
    • INTERACTION
    DNA
    RNA
    small molecule
    protein
  • TMEM30A interacting with ATP8A1 and ATP8A2 (are translocated from the ER to the Golgi complex and plasma membrane upon coexpression of TMEM30A
  • interaction with TMEM30A (is the beta-subunit of ATP8A2 and is crucial for the correct folding, stable expression, export from endoplasmic reticulum, and phosphatidylserine flippase activity of ATP8A2)
