The maternal gene bicoid (bcd) organizes anterior development in Drosophila. Its mRNA is localized at the anterior tip of the oocyte and early. Request PDF on ResearchGate | A gradient of Bicoid protein in Drosophila embryos | The maternal gene bicoid (bcd) organizes anterior. A gradient in concentration of the protein product of the bicoid gene is a determinant of the anterior–posterior axis of Drosophila embryos.

Bicoid (gene) – Wikipedia

A gradient of bicoid protein in Drosophila embryos. Bicoid is one of few proteins which binds both RNA and DNA targets using its homeodomain to regulate embtyos transcription and translation, respectively. Phosphorylation of bicoid on MAP-kinase sites: The protein is concentrated in the nuclei of cleavage stage embryos.

This protein is absent or reduced in embryonic extracts of nine of the 11 bcd alleles. Journal of Molecular Biology.

Proceedings of the National Academy of Sciences. Morphogenesis, plasticity and irreversibility. 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.
