This page was last edited on 3 Novemberat Bicoid is one of few proteins which binds both RNA and DNA targets using its homeodomain to regulate their transcription and translation, respectively. The nucleic acid-binding homeodomain of Bicoid has been solved by NMR.

This paper has been referenced on Twitter 2 times over the past 90 days. The synthesis-diffusion-degradation model explains Bicoid gradient formation in unfertilized eggs. Mechanisms that have been proposed to effect this scaling include non-linear degradation of Bicoid,  nuclear retention as a size-dependent regulator of Bicoid protein’s effective diffusion coefficient,   and scaling of cytoplasmic streaming.
Bicoid is a maternal effect gene whose protein concentration gradient patterns the anterior-posterior A-P axis during Drosophila embryogenesis. This paper has highly influenced 24 other papers.
