CC   -!- FUNCTION: Cell surface transmembrane ligand for Eph receptors, a family
CC       of receptor tyrosine kinases which are crucial for migration, repulsion
CC       and adhesion during neuronal, vascular and epithelial development
CC       (PubMed:7929389, PubMed:10704386). Binding to Eph receptors residing on
CC       adjacent cells leads to contact-dependent bidirectional signaling into
CC       neighboring cells (PubMed:7929389, PubMed:10704386). Shows high
CC       affinity for the receptor tyrosine kinase EPHB1/ELK (By similarity).
CC       Can also bind EPHB2 and EPHB3 (PubMed:7929389). Binds to, and induces
CC       the collapse of, commissural axons/growth cones in vitro
CC       (PubMed:10704386). May play a role in constraining the orientation of
CC       longitudinally projecting axons (PubMed:10704386).
CC       {ECO:0000250|UniProtKB:P98172, ECO:0000269|PubMed:10704386,
CC       ECO:0000269|PubMed:7929389}.
CC   -!- SUBUNIT: Interacts (via PDZ-binding motif) with GRIP1 and GRIP2 (via
CC       PDZ domain 6) (By similarity). Interacts with TLE1 (PubMed:21429299).
CC       The intracellular domain peptide interacts with ZHX2; the interaction
CC       enhances ZHX2 transcriptional repression activity (PubMed:19515908).
CC       {ECO:0000250|UniProtKB:P98172, ECO:0000269|PubMed:19515908,

CC       P52795; O08992: Sdcbp; NbExp=3; IntAct=EBI-8107507, EBI-538265;
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000269|PubMed:7929389,
CC       ECO:0000305|PubMed:10704386}; Single-pass type I membrane protein
CC       {ECO:0000255}. Membrane raft {ECO:0000269|PubMed:10197531}. Note=May
CC       recruit GRIP1 and GRIP2 to membrane raft domains.
CC       {ECO:0000269|PubMed:10197531}.
CC   -!- SUBCELLULAR LOCATION: [Ephrin-B1 C-terminal fragment]: Cell membrane
CC       {ECO:0000250|UniProtKB:P98172}; Single-pass type I membrane protein
CC       {ECO:0000255}.
CC   -!- SUBCELLULAR LOCATION: [Ephrin-B1 intracellular domain]: Nucleus
CC       {ECO:0000269|PubMed:19515908}. Note=Colocalizes with ZHX2 in the
CC       nucleus. {ECO:0000269|PubMed:19515908}.
CC   -!- TISSUE SPECIFICITY: Expressed on lateral floor plate cells,
CC       specifically on commissural axon segments that have passed through the
CC       floor plate. Expressed in cells of the retinal ganglion cell layer
CC       during retinal axon guidance to the optic disk (PubMed:10704386).
CC       Expressed in myogenic progenitor cells (PubMed:27446912).
CC       {ECO:0000269|PubMed:10704386, ECO:0000269|PubMed:27446912}.
CC   -!- DEVELOPMENTAL STAGE: Expressed in the floor plate throughout the period
CC       of commissural axon pathfinding (PubMed:10704386). In myogenic
CC       progenitor cells, highly expressed during early development (11.5 dpc)
CC       and progressively repressed as developments proceeds (PubMed:27446912).
CC       {ECO:0000269|PubMed:10704386, ECO:0000269|PubMed:27446912}.
CC   -!- PTM: Inducible phosphorylation of tyrosine residues in the cytoplasmic
CC       domain. {ECO:0000250|UniProtKB:P98172}.
CC   -!- PTM: Proteolytically processed. The ectodomain is cleaved, probably by
CC       a metalloprotease, to produce a membrane-tethered C-terminal fragment.
CC       This fragment is then further processed by the gamma-secretase complex
CC       to yield a soluble intracellular domain peptide which can translocate
CC       to the nucleus. The intracellular domain peptide is highly labile
CC       suggesting that it is targeted for degradation by the proteasome.
CC       {ECO:0000250|UniProtKB:P98172}.
CC   -!- SIMILARITY: Belongs to the ephrin family. {ECO:0000255|PROSITE-
CC       ProRule:PRU00884}.
