The Drosophila fish-hook gene encodes a HMG domain protein essential for segmentation and CNS development
P.A. Nambu, J.R. Nambu
Development 1996 122: 3467-3475;

Summary

We describe the isolation and analysis of the Drosophila fish-hook (fish) gene, which encodes a novel member of the SOX subgroup of High Mobility Group (HMG) domain proteins that exhibit similarity to the mammalian testis determining factor, SRY. The fish gene is initially expressed in a pair-rule-like pattern which is rapidly replaced by strong neuroectoderm expression. fish null mutants exhibit severe segmentation defects, including loss and/or fusion of abdominal denticle belts and stripe-specific defects in pair-rule and segment polarity gene expression.fish mutant embryos also exhibit loss of specific neurons, fusion of adjacent ventral nerve cord ganglia and aberrant axon scaffold organization. These results indicate an essential role for fish in anterior/posterior pattern formation and nervous system development, and suggest a potential function in modulating the activities of gap and pair-rule proteins.

The Node is looking for a new Community Manager!

If you're interested in science communication, publishing and the developmental biology community, we're hiring for a new Community Manager for our community site, the Node.

The position is an exciting opportunity to develop an already successful and well-known site, engaging with the academic, publishing and online communities. Find out more and how to apply.

Upcoming special issue: call for papers

The Immune System in Development and Regeneration
Guest editors: Florent Ginhoux and Paul Martin
Submission deadline: 1 September 2021
Publication: Spring 2022

The special issue welcomes Review articles as well as Research articles, and will be widely promoted online and at key global conferences.

The people behind the papers - Clément Dubois, Shivam Gupta, Andrew Mugler and Marie-Anne Félix

A new paper investigates the robustness of neuroblast migration in the C. elegans larva in the face of both genetic and environmental variation. In an interview, the paper's four authors tell us more about the story.

Development presents...

Our successful webinar series continues into 2021, with early-career researchers presenting their papers and a chance to virtually network with the developmental biology community afterwards. Every talk is recorded and since launching in August last year, the series has clocked up almost 10k views on YouTube.

Here, Swann Floc'hlay discusses her work modelling dorsal-ventral axis specification in the sea urchin embryo.
