Pre-B-cell leukemia transcription factor 1 is a protein that in humans is encoded by the PBX1 gene .[5] extradenticle , and causes changes in embryonic development.
Function [ edit ]
Mice studies suggest PBX1 is involved in bone generation and skeletal patterning.[6]
Interactions [ edit ]
PBX1 has been shown to interact with:
Fruit fly homolog [ edit ]
The Drosophila melangoster extradenticle encodes a homeodomain protein that is 71% similar to the Pbx1 protein, and is considered homologous to PBX1.[14] homeodomain transcription factor [15] embryogenesis and is related to morphological changes and development.[14]
Reduced levels of extradenticle cause segmental transformations, without affecting the functionality or location of homeotic genes. Complete removal of extradenticle both maternally and zygotically leads to alterations from failure of non-extradenticle protein expression.[16]
A monoclonal antibody study of the expression of extradenticle protein in embryonic development found that it is uniformly distributed, as well as excluded from cell nuclei, until gastrulation . During the germ band retraction stage of development, extradenticle protein begins to accumulate in the nuclei of cells in a specific pattern. Proximal areas of wing and leg imaginal discs have extradenticle present in the nucleus, while distal areas only have it in the cytoplasm.[17]
