GO Classification
Functions
ATP binding / ephrin receptor activity / GPI-linked ephrin receptor activity / transmembrane-ephrin receptor activity
Processes
axon guidance / cAMP-mediated signaling / ephrin receptor signaling pathway / hippocampus development / neuron development / positive regulation of CREB transcription factor activity / regulation of actin cytoskeleton organization / regulation of GTPase activity / regulation of insulin secretion involved in cellular response to glucose stimulus
Components
axon / dendrite / external side of plasma membrane / integral component of plasma membrane / neuronal cell body / perinuclear region of cytoplasm / plasma membrane / rough endoplasmic reticulum
General Function
Transmembrane-ephrin receptor activity
Specific Function
Receptor tyrosine kinase which binds promiscuously GPI-anchored ephrin-A family ligands residing on adjacent cells, leading to contact-dependent bidirectional signaling into neighboring cells. The signaling pathway downstream of the receptor is referred to as forward signaling while the signaling pathway downstream of the ephrin ligand is referred to as reverse signaling. Among GPI-anchored ephrin-A ligands, EFNA5 most probably constitutes the cognate/functional ligand for EPHA5. Functions as an axon guidance molecule during development and may be involved in the development of the retinotectal, entorhino-hippocampal and hippocamposeptal pathways. Together with EFNA5 plays also a role in synaptic plasticity in adult brain through regulation of synaptogenesis. In addition to its function in the nervous system, the interaction of EPHA5 with EFNA5 mediates communication between pancreatic islet cells to regulate glucose-stimulated insulin secretion (By similarity).
