Antibodies raised against bcd fusion proteins recognize a kd doublet band in Western blots of extracts of hr old embryos.
A gradient of bicoid protein in Drosophila embryos.
This protein is absent or reduced in embryonic extracts of nine of the 11 bcd alleles. Journal of Molecular Biology. This paper has highly influenced 24 other papers.
Comparative phylogenetic  and experimental evolution  studies suggest an inherent mechanism for robust generation of a scaled Bicoid protein gradient. Phosphorylation of bicoid on MAP-kinase sites: DroccoEric F.

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. Morphogenesis, plasticity and irreversibility.
Tank Physical biology The protein is concentrated in the nuclei of cleavage stage embryos. The nucleic acid-binding homeodomain of Bicoid has been solved by NMR.
Animal developmental biology Drosophila melanogaster genes. A gradient of bicoid protein in Drosophila embryos. Bicoid is a maternal effect gene whose protein concentration gradient patterns the anterior-posterior A-P axis during Drosophila embryogenesis. Views Read Edit View history. Bicoid is one of bicood proteins which binds both RNA and DNA targets using its homeodomain to regulate their transcription and translation, respectively.
