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.

WD40 domain, found in a number of eukaryotic proteins that cover a wide variety of functions including adaptor/regulatory modules in signal transduction, pre-mRNA processing and cytoskeleton assembly; typically contains a GH dipeptide 11-24 residues from its N-terminus and the WD dipeptide at its C-terminus and is 40 residues long, hence the name WD40; between GH and WD lies a conserved core; serves as a stable propeller-like platform to which proteins can bind either stably or reversibly; forms a propeller-like structure with several blades where each blade is composed of a four-stranded anti-parallel b-sheet; instances with few detectable copies are hypothesized to form larger structures by dimerization; each WD40 sequence repeat forms the first three strands of one blade and the last strand in the next blade; the last C-terminal WD40 repeat completes the blade structure of the first WD40 repeat to create the closed ring propeller-structure; residues on the top and bottom surface of the propeller are proposed to coordinate interactions with other proteins and/or small ligands; 7 copies of the repeat are present in this alignment.

WD repeat-containing protein 74; WDR74 (WD repeat-containing protein 74) from mammals and plants is an essential factor for ribosome assembly. In cooperation with the assembly factor NVL2, WDR74 participates in an early cleavage of the pre-rRNA processing pathway. NVL2 is a type II double ring, AAA-ATPase, that may mediate the release of WDR74 from nucleolar pre-60S particles. WDR74 has been implicated in tumorigenesis. In lung cancer, it regulates cell proliferation, cell cycle progression, chemoresistance and cell aggressiveness, by inducing nuclear beta-catenin accumulation and driving downstream Wnt-responsive genes expression. In melanoma, it promotes apoptosis resistance and aggressive behavior by regulating the RPL5-MDM2-p53 pathway. WDR74 contains an N-terminal seven-bladed beta-propeller WD40 domain that associates with the D1-AAA domain of the AAA-ATPase NVL2, and a flexible lysine-rich C-terminus that extends outward from the WD40 domain, and is required for nucleolar localization.
