HELP motif; The founding member of the EMAP protein family is the 75 kDa Echinoderm Microtubule-Associated Protein, so-named for its abundance in sea urchin, sand dollar and starfish eggs. The Hydrophobic EMAP-Like Protein (HELP) motif was identified initially in the human EMAP-Like Protein 2 (EML2) and subsequently in the entire EMAP Protein family. The HELP motif is approximately 60-70 amino acids in length and is conserved amongst metazoans. Although the HELP motif is hydrophobic, there is no evidence that EMAP-Like Proteins are membrane-associated. All members of the EMAP-Like Protein family, identified to-date, are constructed with an amino terminal HELP motif followed by a WD domain. In C. elegans, EMAP-Like Protein-1 (ELP-1) is required for touch sensation indicating that ELP-1 may play a role in mechanosensation. The localization of ELP-1 to microtubules and adhesion sites implies that ELP-1 may transmit forces between the body surface and the touch receptor neurons.

trimerization domain of the echinoderm microtubule-associated protein-like family; The echinoderm microtubule-associated protein (EMAP)-like (EML) family includes EMAP-1, EMAP-2, EMAP-3, and EMAP-4. EMAP-1, also called EMAL1, EMAPL or EMAPL1, 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. It is required for normal proliferation of neuronal progenitor cells in the developing brain and for normal brain development. EMAP-2, also called EML2 or EMAPL2, is a tubulin binding protein that inhibits microtubule nucleation and growth, resulting in shorter microtubules. EMAP-3, also called EML3, is a nuclear microtubule-binding protein required for the correct alignment of chromosomes in metaphase. EMAP-4, also called EML4, EMAPL4, restrictedly overexpressed proliferation-associated protein, or Ropp 120, may modify the assembly dynamics of microtubules, such that microtubules are slightly longer, but more dynamic. This model corresponds to a conserved trimerization domain located at the N-terminus of EML family members.
