homeobox sequence: highly conserved sequence of 180 base pairs found within genes that are involved in regulating anatomical development in plants, animal and fungi
hox genes:
subset of homeobox genes found only in animals
involved in formation of anatomical features in correct location of body plan
code for homeodomain proteins
homeodomain proteins: proteins that act as transcription factors to activate or repress genes that regulate mitosis, apoptosis and cell cycle.
homeodomain:
hox genes have homeobox sequences that code for homeodomains
this part of a protein binds to a transcription factor
this can activate or repress the developmental genes
