Symbol GOLGA4 contributors: mct/npt - updated : 03-03-2015
HGNC name golgi autoantigen, golgin subfamily a, 4
HGNC id 4427
PROTEIN
PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • coiled-coil structure stabilized by heptad repeats, granin motif
  • a RAB6 interaction domain
  • a C terminal Golgi localization domain (GLD), that associate with the trans-Golgi network (TGN) via a GRIP domain, and GRIP domains of GOLGA4 and GOLGA1 bind discriminately to distinct membrane subdomains of the TGN
  • HOMOLOGY
    Homologene
    FAMILY
  • golgin subfamily

    text
  • trans Golgi
  • GOLGA1, GOLGA4 are targeted to the Golgi membrane through their GRIP domains
  • ARFRP1 and GOLGA4 were detected in the same compartment close to the nucleus, presumably the trans-Golgi
  • basic FUNCTION
  • Golgi complex antigen targeted by autoantibodies associated with Sjogren syndrome
  • GOLGA1, GOLGA4, GCC1, GCC2 can self-associate to form homodimers exclusively
  • functions in Golgi positioning indirectly, probably by regulating retrograde movement of cargo required for recruitment or activation of dynein-dynactin complexes on newly formed Golgi elements
  • key regulator of TNF secretion and LPS activation of macrophages results in increased Golgi carriers for export
  • coiled-coil protein that recycles between the cytosol and buds/vesicles of the TGN and which plays a fundamental role in trafficking transport vesicles
