WD40 repeat domain-containing protein folds into a beta-propeller structure and functions as a scaffold, providing a platform for the interaction and assembly of several proteins into a signalosome; similar to Schizosaccharomyces pombe ribosome biogenesis protein nsa1 involved in the biogenesis of the 60S ribosomal subunit

Ribosome biogenesis protein Nsa1 and similar proteins; Ribosome biogenesis protein Nsa1 (Nop7-associated 1) from fungi and WDR74 (WD repeat-containing protein 74) from mammals and plants, are homologous essential factors for ribosome assembly. In cooperation with the assembly factor Rix7/NVL2, Nsa1/WDR74 participates in an early cleavage of the pre-rRNA processing pathway. Rix7/NVL2 is a type II double ring, AAA-ATPase, that may mediate the release of Nsa1/WDR74 from nucleolar pre-60S particles. Nsa1/WDR74 contains an N-terminal seven-bladed beta-propeller WD40 domain that associates with the D1-AAA domain of the AAA-ATPase Rix7/NVL2, and a flexible lysine-rich C-terminus that extends outward from the WD40 domain, and is required for nucleolar localization.

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.

Rix7 is a type II double ring, AAA-ATPase, that may mediate the release of Nsa1 from nucleolar pre-60S particles. The release of Nsa1 from a discrete preribosomal particle may trigger the progression of 60S ribosome biogenesis. Nsa1 is essential for cell viability in yeast.

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.

(specific hits) are drawn in bright colors.
Others (non-specific hits) and
superfamily placeholders are drawn in pastel colors.
