Developmental Signals - Homeobox
The family of homeobox (Hox) proteins has been a focus of research for over 30 years. This family of genes were also the basis of the embryo patterning studies that led to the Nobel Prize in Medicine 1995. We now know that in addition to whole embryo axes patterning, this family of genes has many roles in establishing pattern throughout the embryo in different tissues and organs.
This signalling pathway has also been implicated in many developmental abnormalities and diseases.
