Echinoderm microtubule-associated protein-like 1

Gene

EML1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Modulates the assembly and organization of the microtubule cytoskeleton, and probably plays a role in regulating the orientation of the mitotic spindle and the orientation of the plane of cell division. Required for normal proliferation of neuronal progenitor cells in the developing brain and for normal brain development. Does not affect neuron migration per se.By similarity

Involvement in diseasei

Band heterotopia (BH)1 Publication
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA brain malformation of the lissencephaly spectrum, resulting from disordered neuronal migration and characterized by bands of gray matter interposed in the central white matter. Disease features include severe developmental delay with intellectual disability, enlarged head circumference, periventricular and ribbon-like subcortical heterotopia, polymicrogyria and agenesis of the corpus callosum.
