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.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
