WD proteins are made up of highly conserved repeating units usually ending with Trp-Asp (WD). They are found in all eukaryotes but not in prokaryotes. They regulate cellular functions, such as cell division, cell-fate determination, gene transcription, transmembrane signalling, mRNA modification and vesicle fusion. Here we define the common features of the repeating units, and criteria for grouping such proteins into functional subfamilies.

WD-repeat protein encoding genes among prokaryotes of theStreptomyces genus
Southern hybridization with probes designed for detection of WD-repeats coding sequences gave positive results in 21 streptomycete strains indicating that WD-repeats encoding genes are massively…
GTP-binding proteins in plants
TLDR
Current progress in the molecular characterization and functional analysis of plant genes encoding heterotrimeric and small GTPases is discussed and a systematic classification is proposed.
The WD-repeat protein superfamily in Arabidopsis: conservation and divergence in structure and function
TLDR
Most Arabidopsis WDR proteins are strongly conserved across eukaryotes, including those that have been found to play key roles in plant-specific processes, with diversity in function conferred at least in part by divergence in upstream signaling pathways, downstream regulatory targets and /or structure outside of the WDR regions.
A deduced Thermomonospora curvata protein containing serine/threonine protein kinase and WD-repeat domains
TLDR
The gene pkwA coding for a typical WD-repeat protein was found in the chromosome of the bacterium Thermomonospora curvata CCM 3352, where it was found to be confined to eukaryotes.
Human Genome and Diseases:¶WD-repeat proteins: structure characteristics, biological function, and their involvement in human diseases
TLDR
It is paramount to uncover the function of individual WD-repeat proteins, explore the protein interaction mechanism through WD- repeat domains and, ultimately, understand the complex biological processes and organisms themselves.
ZFWD: a novel subfamily of plant proteins containing a C3H zinc finger and seven WD40 repeats.
Wdr12, a mouse gene encoding a novel WD-Repeat Protein with a notchless-like amino-terminal domain.
TLDR
The cloning of a mouse cDNA is reported, referred to as Wdr12, which encodes a novel WD-repeat protein of 423 amino acids, predicted to contain seven WD units and a nuclear localization signal located within a protruding peptide between the third and fourth WD domains.
Residues in the WD repeats of Tup1 required for interaction with alpha2
TLDR
The yeast transcriptional repressor Tup1 contains seven WD repeats which interact with the DNA-binding protein alpha2, and mutations in Tup1 that disrupt this interaction are identified, suggesting that a similar structural interface is formed by WD repeat proteins that are used in both transcriptional regulation and signal transduction.
WD40 Repeat Proteins: Signalling Scaffold with Diverse Functions
TLDR
The review summarizes the vast array of functions performed by different WD40 domain containing proteins, their domain organization and functional conservation during the course of evolution.
The amino terminal domain of a novel WD repeat protein from Trypanosoma cruzi contains a non-canonical mitochondrial targeting signal.

It is proposed that G-protein heterotrimers are formed when this beta-subunit couples with each of the eight distinct G- protein alpha-subunits that are transiently expressed during development.

TLDR
The absence of DNA-binding motifs and the presence of these repeated domains suggest that the CYC8 and TUP1 proteins function via protein-protein interaction with transcriptional regulatory proteins.
