How do Hox proteins function

By | May 2, 2021

The enormous diversity in body plan among the various organisms in animal kingdom is partly contributed by the Hox genes.Hox proteins regulate gene expression in different ways and thereby generating different body plans.Most of the organisms on earth have one or more clusters of Hox genes.These Hox genes pattern different segment and thus gives a… Read More »

How a single Hox gene (Ultrabithorax) can specify two different morphologies ?

By | April 20, 2021

Bithorax complex in Drosophila consists of three homeodomain encoding proteins : Ultrabithorax (Ubx), abdominal-A (abd-A) and Abdominal-B (Abd-B). The function of these bithorax genes is to pattern entire abdomen ( A1-A9 segments ) and a part of third thoracic segment ,which happens to be their normal expression domain in embryos. These Hox proteins are expressed… Read More »
