    SUBCELLULAR LOCALIZATION     plasma membrane
    basic FUNCTION
  • may be playing a role in a signal transduction process involved in hindbrain pattern formation
  • playing a role in local neuronal circuits that control walking
  • involved in neurite outgrowth, early neuronal cell development, neuropeptide signaling/synthesis and neuronal receptor
  • EFNA5-EPHA4/EPHA5 system plays an important role in the direct pathway-dependent regulation of the substantia nigra pars reticulata in both acute and adaptive cocaine responses
  • CELLULAR PROCESS
    PHYSIOLOGICAL PROCESS
    PATHWAY
    metabolism
    signaling
  • EPHA4/EFNAA3 signaling is potentially a critical mechanism for astrocytes to regulate synaptic function and plasticity
  • a component
    INTERACTION
    DNA
    RNA
    small molecule
    protein
  • interaction between neuronal EPHA4 and glial EFNA3 bidirectionally controls synapse morphology and glial glutamate transport, ultimately regulating hippocampal function
  • mediates at least in part the repulsive effect of EFNA3 in the neurons from the medial ganglionic eminence
  • direct interaction between SIPA1L3 and EPHA4, building a functional platform for proper ocular development
  • cell & other
