Bicoid was also the first protein demonstrated to act as a morphogen. Bicoid is a maternal effect gene whose protein concentration gradient patterns the anterior-posterior A-P axis during Drosophila embryogenesis.

Bicoid is one of few proteins which binds both RNA and DNA targets using its homeodomain to regulate their transcription and translation, respectively. By clicking accept or continuing to use the site, you agree to the terms outlined in our Privacy PolicyTerms of Serviceand Dataset License.

Mechanisms that have been od to effect this scaling include non-linear degradation of Bicoid, [18] nuclear retention as a size-dependent regulator of Bicoid protein’s effective diffusion coefficient, [9] [19] and scaling of cytoplasmic streaming.
