EMX1 (empty spiracles homeobox 1) gene is localized to human chromosome 2p14-p13. It is a late and narrow expression gene. It is a homeodomain transcription factor. It is a human ortholog of ems (empty spiracles) protein found in Drosophila. This protein is a resident of nucleus. In embryos, the expression of this gene is restricted to cerebral cortex and olfactory bulbs.
Synonyms: Anti-Empty spiracles homolog 1 antibody produced in rabbit; Anti-Empty spiracles-like protein 1 antibody produced in rabbit; Anti-Homeobox protein EMX1 antibody produced in rabbit

Application: Anti-EMX1 antibody produced in rabbit, a Prestige Antibody, is developed and validated by the Human Protein Atlas (HPA) project (www.proteinatlas.org). Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.
Biochem Physiol Actions: EMX1 (empty spiracles homeobox 1) interacts with WDR11, which is a part of olfactory neuron development. In developing central nervous system, this protein determines cell fates. It participates in sonic hedgehog-Patched-Gli (Shh-Ptch-Gli) signaling pathway, where it acts as an effector protein for Gli-Kruppel family member 3. EMX1-lineage derived cells are responsible for two types of neuronal population in mature basal forebrain namely, a subclass of distinct amygdala excitatory neurons, and medium spiny neurons (MSNs) in the striatum. Thus, this protein determines the striatum and amygdala fate of developing neurons.
