Its mRNA is localized at the anterior tip of the oocyte and early embryo. Comparative phylogenetic [16] and experimental evolution [17] studies suggest an inherent mechanism for robust generation of a scaled Bicoid protein gradient. From This Paper Topics from this paper.

Journal of Molecular Biology. Bicoid is a maternal effect gene whose protein concentration gradient patterns the graddient A-P axis during Drosophila embryogenesis.

Topics Discussed in This Paper. Tank Physical biology Views Read Edit View history. The nucleic acid-binding homeodomain of Bicoid has been solved by NMR. This paper has highly influenced 24 drosohila papers. Bicoid was also the first protein demonstrated to act as a morphogen.

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