The following text describes a protein:
Function:
Component of the extracellular signaling pathway that establishes the dorsal-ventral pathway of the embryo. A protease cascade involving ndl, gd, snk and ea results in activation of the spz Toll receptor ligand; acts upstream of gd, snk and ea and is required for proteolytic processing of gd. Activation of ea requires activation of the ndl-gd-snk protease cascade and sulfation of a vitelline membrane component by pip. Localized activation of the Toll receptor in the ventral region of the embryo defines cell identities along the dorsal-ventral continuum (Probable).
Subcellular Localization:
Secreted, extracellular space, extracellular matrix.
