PROTEIN
PHYSICAL PROPERTIES
STRUCTURE
motifs/domains
  • GTPase domain made of three regions named switches 1,2 and 3 and including the sites for guanine nucleotide binding and effector interaction
  • an helical domain
    • mono polymer heteromer , trimer
    HOMOLOGY
    interspecies homolog to murine Gna14
    homolog to C.elegans mo1d7.7
    Homologene
    FAMILY
  • G-alpha family
  • G(q) subfamily
    • CATEGORY signaling , receptor membrane G
    SUBCELLULAR LOCALIZATION extracellular
        plasma membrane
        intracellular
    basic FUNCTION
  • mediating pertussis toxin-resistant stimulation of phospholipase C beta
  • cell fate specification
  • palmitoylated at distinct polycysteine sequences, and the adjacent polybasic domain is not required for Galpha palmitoylation but is important for localization and functional activity of heterotrimeric G proteins
  • GNA12 and GNA14 play a key role in the genetic architecture underlying normal gray matter density (GMD) variation in frontal and parietal regions
  • GNA11 and GNA14 induce changes in cellular morphology and growth-factor independence via MAPK activation
    • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling signal transduction
    a component
  • heterotrimeric G protein GTPase, alpha subunit
    • INTERACTION
    DNA
    RNA
    small molecule nucleotide,
  • GTP
    • protein
  • beta and gamma subunits of the trimeric G protein
  • TTC1 is required for GNA14 to stimulate RAS-dependent signaling pathways, but not for the propagation of signals along RAS-independent pathways
  • previously identified PLCB1-interacting AAs are insufficient to ensure productive interaction of GNA14 with PLCB1, while an intact N-terminal half of GNA14 is apparently required for PLCB1 interaction
