Enables GPI-linked ephrin receptor activity. Involved in several processes, including ephrin receptor signaling pathway; nervous system development; and regulation of insulin secretion involved in cellular response to glucose stimulus. Acts upstream of or within cellular response to follicle-stimulating hormone stimulus and cellular response to forskolin. Located in adherens junction and cell periphery. Is expressed in several structures, including future midbrain; genitourinary system; nervous system; sensory organ; and upper jaw. Orthologous to human EPHA5 (EPH receptor A5).
