EPHB2

A gene on chromosome 1p36.1-p35 that encodes a member of the ephrin-B receptor subfamily of receptor tyrosine kinases, which “promiscuously” bind membrane-bound ephrin-B family ligands residing on adjacent cells, leading to contact-dependent bidirectional signalling into neighbouring cells. EPHB2 functions in axon guidance during development, guiding commissural axons and forming a major interhemispheric connection between the two temporal lobes of the cerebral cortex. EPHB2 is also involved in the guidance of contralateral inner ear efferent growth cones at the midline, and of retinal ganglion cell axons to the optic disk. It also regulates dendritic spines development and maturation, and it stimulates the formation of excitatory synapses.

Activation of EPHB2 by EFNB1 abolishes the ARHGEF15-mediated negative regulation on excitatory synapse formation. EPHB2 also controls other aspects of development, including angiogenesis, palate development, as well as inner ear development by regulating endolymph production. It may act as a tumour suppressor.

Molecular pathology
Defects in EPHB2 have been linked to prostate cancer.

Definition 1--Consolidation: A consolidation is an improvement of the CAPB of at least 1.
5 per cent of GDP improvement in the CAPB was chosen for three reasons.
Definition 2--Success: A consolidation in line with Definition 1 is deemed successful if the following condition applies; in the three years after the end of the consolidation episode the CAPB does not deteriorate by more than 0.
In close to 70 per cent of the years featuring a consolidation episode in line with Definition 1, the CAPB improved by 1.
However, the CAPB method shows the opposite; that is, unsuccessful consolidations "come out of the blocks faster" with larger initial reductions in primary budget deficits, but do not lead to lasting reductions in debt.
Based on the CAPB method, the smallest share of expenditures in successful consolidations across all of our definitions of success is slightly under 93 percent and the highest is slightly under 120 percent.
Using the CAPB method for identifying consolidations and a range of definitions of success, social transfer reductions make up no less than 36 percent of the overall deficit reduction for successful consolidations.
