Embryotoxins

Embryotoxins are a group of proteins produced by the *Embryosac-specific protein 1* gene, also known as *Eph-ephrin signaling* in a developmental context. These proteins play a critical role in early embryonic development, particularly in the formation of the central nervous system and other vital organs. They are involved in cell-cell signaling pathways that regulate cell proliferation, differentiation, and migration.

Specifically, embryotoxins are part of the ephrin family of ligands, which bind to Eph receptor tyrosine kinases. This interaction triggers a cascade of intracellular events that guide the precise positioning and organization of cells during embryogenesis. Disruptions in embryotoxin function or signaling can lead to severe developmental abnormalities, highlighting their essential nature for normal fetal development. Research into embryotoxins contributes to our understanding of developmental biology and may offer insights into congenital disorders.
