Expressioni

Tissue specificityi

Ubiquitously expressed during early stages of embryogenesis, but the effect on development appears graded and is restricted to the dorsal side of the embryo.1 Publication

Developmental stagei

Expressed both maternally and zygotically. Highest embryonic expression is found during syncytial blastoderm (nuclear cycles 11-12). Expression declines rapidly at cellular blastoderm stage 5 and is not detected during the rest of embryonic development.1 Publication

Interactioni

Subunit structurei

Heterodimers of scw/dpp are the active subunit, dpp/dpp homodimers elicit a basal response and scw/scw homodimers alone are ineffective in specifying a dorsal pattern.
