Bicoid is one of few proteins which binds both RNA and DNA targets using its homeodomain to regulate their transcription and translation, respectively. Bicoid protein gradient formation is one of the earliest steps in fruit fly embryo A-P patterning: Mechanisms that have been proposed 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.


Views Read Edit View history. Journal of Molecular Biology. The synthesis-diffusion-degradation model explains Bicoid gradient formation in unfertilized eggs. Formation of the bicoid morphogen gradient: This paper has highly influenced 24 other papers. The nucleic acid-binding homeodomain of Bicoid has been solved by NMR. Bicoid is a maternal effect gene whose protein concentration gradient patterns the anterior-posterior A-P axis during Drosophila embryogenesis.
