Multiple regulatory elements, best defined in Drosophila melanogaster, ensure that Hox expression patterns follow the spatial and temporal colinearity reflected in their tight genomic organization. However, the precise mechanisms that regulate colinear patterns of Hox gene expression remain unclear, especially in higher vertebrates where it is not fully determined how the distinct activation domains of the tightly clustered Hox genes are defined independently of each other. Here, we report the identification of a large number of novel cis-elements at mammalian Hox clusters that can help in regulating their precise expression Epigenetics & chromatin8https://www.ebi.ac.uk/biostudies/studies/S-EPMC3639804biostudies-literatureVertebrate GAGA factor associated insulator elements demarcate homeotic genes in the HOX clusters.PMC3639804Srivastava SMishra RKGarapati HSPuri DDhawan JfalseVertebrate GAGA factor associated insulator elements demarcate homeotic genes in the HOX clusters.<h4>Background</h4>Hox genes impart segment identity to body structures along the anterior-posterior axis and are crucial for the proper development of all organisms.
