WDR1/Aip1 functions as a co-factor of cofilin to accelerate actin filament severing and depolymerization; loss-of-function (hypomorphic alleles) in mice causes macrothrombocytopenia due to megakaryocyte maturation defects and autoinflammatory disease with impaired cytoskeletal responses in neutrophils, establishing an essential in vivo role for the cofilin/WDR1 complex in actin dynamics in these cell types. |

Biallelic loss-of-function mutations in WDR1 in human patients cause elevated F-actin content (fourfold increase) in neutrophils, markedly impaired chemotaxis, cell polarization, and spreading, and a distinctive nuclear herniation phenotype, confirming that WDR1-dependent actin depolymerization is required for normal neutrophil morphology and motility. |

A homozygous missense mutation in WDR1 causes autoinflammatory disease with elevated IL-18 (but not IL-1β) and increased caspase-1 cleavage in patient monocytes; mutant WDR1 protein forms aggregates that accumulate pyrin in transfected HEK293T cells, suggesting that impaired actin dynamics precipitates inflammasome assembly. |

Suppression of AIP1/WDR1 causes mitotic cell flattening instead of normal rounding; in vitro filament severing/disassembly assays showed that AIP1/WDR1 abolishes residual actin-severing activity of phosphorylated cofilin, indicating that WDR1 is required to fully suppress actin turnover and thereby enable mitotic cell rounding. |

Wdr1 (Aip1), an F-actin-binding protein that enhances cofilin/destrin-mediated F-actin disassembly, is required for actomyosin remodeling, cortical tension generation, and the cell shape changes that establish planar cell polarity (PCP) in developing mouse epidermis; Wdr1 depletion alone recapitulates core PCP mutations. |

WDR1 knockdown in megakaryoblastic MEG-01 cells increases F-actin content, adhesion, spreading, and basal intracellular calcium, and produces fewer but larger platelet-like particles with enhanced adhesion; WDR1 overexpression reverses these phenotypes, demonstrating that WDR1 suppresses platelet activity by regulating actin cytoskeleton dynamics. |

In Wdr1-hypomorphic mouse platelets, actin turnover (F-actin/G-actin ratio) is impaired during collagen- and thrombin-induced aggregation, integrin αIIbβ3 inside-out activation is defective despite normal calcium responses, and talin fails to redistribute to the cytoskeleton, establishing that WDR1-mediated actin remodeling is required for talin-dependent αIIbβ3 activation. |

Wdr-1 co-localizes with cofilin-1 in cortical actin of resting platelets and translocates together with cofilin-1 to the cytoskeleton upon fibrinogen adhesion; in Wdr-1-deficient platelets cofilin-1 is aberrantly distributed throughout the cytoplasm, F-actin fails to attach to focal adhesion kinase, and clot retraction and spreading are impaired, demonstrating that Wdr-1 is required for cofilin-1 localization to the membrane skeleton and F-actin–focal adhesion interaction. |

EYA3 tyrosine phosphatase dephosphorylates WDR1 on tyrosine residues that are phosphorylated by Src kinase; loss of WDR1 tyrosine phosphorylation causes major changes to the cellular actin cytoskeleton, identifying WDR1 as an EYA3-specific substrate and placing Src/EYA3 as writer/eraser of WDR1 phosphorylation in cytoskeletal regulation. |

In Wdr1-deficient zebrafish neutrophils, cofilin is predominantly unphosphorylated and associated with F-actin, displacing myosin; this leads to F-actin cytoplasmic aggregates, loss of phospho-myosin cortical localization, nuclear disorganization, and eruptive cell death. Depletion of coronin 1A fully rescues cortical F-actin distribution, nuclear integrity, viability, and mobility in Wdr1-deficient neutrophils, establishing a functional interplay between Wdr1, cofilin, and coronin 1A in regulating F-actin and actomyosin contractility. |

Wdr1 and LIMK have distinct roles in BCR-induced actin remodeling at the B cell immune synapse: Wdr1 enhances cofilin-mediated actin disassembly while LIMK phosphorylates and inactivates cofilin; both the Wdr1-LIMK-cofilin axis collectively controls peripheral actin assembly, B cell spreading, and actin-dependent amplification of BCR signaling. |

In response to dimethyl fumarate (Tecfidera), Keap1-specific modification triggers dissociation of Wdr1 from Keap1; released Wdr1 then coordinates with cofilin to intercept Bax, driving mitochondrial-targeted apoptosis specifically in neutrophils and macrophages in a process largely independent of canonical Nrf2 signaling. |

WDR1 promotes nuclear import of MRTF-A by affecting expression of importin nuclear transport protein, thereby enhancing MRTF-A-induced breast cancer cell migration via RhoA-MRTF-A signaling; MRTF-A in turn drives expression of miR-206 which feeds back to suppress WDR1 and MRTF-A via their 3'UTRs. |
