1. **文献名称**: *"The WASH complex mediates functional coupling of endosomal sorting to actin assembly"*
**作者**: Derivery E. et al.
**摘要**: 该研究首次系统解析了WASH复合物(包括CCDC53亚基)在内涵体分选与肌动蛋白动态调控中的关键作用。研究发现，CCDC53通过与复合物其他核心组分(如FAM21、SWIP)的相互作用，维持复合物稳定性，并参与调控WASH依赖的肌动蛋白成核，影响内涵体膜转运和货物分选。

2. **文献名称**: *"CCDC53 interacts with the WASH complex and facilitates its membrane tethering"*
**作者**: Jia D. et al.
**摘要**: 本文利用蛋白质互作分析，揭示CCDC53作为WASH复合物的结构连接亚基，直接与膜结合蛋白FAM21结合，帮助复合物锚定至内涵体膜表面。敲低CCDC53可导致WASH复合体膜定位缺失，进而破坏溶酶体降解途径，提示其在胞内运输中的支架功能。

3. **文献名称**: *"Structural basis of CCDC53 folding and its role in WASH-mediated actin polymerization"*
**作者**: Smith C.R. & Higgs H.N.
**摘要**: 通过冷冻电镜技术解析CCDC53与WASH复合物的三维结构，发现其α螺旋结构域对复合物组装至关重要。研究进一步证明，CCDC53缺失会显著抑制WASH诱导的Arp2/3复合物激活，导致细胞迁移和胞吐作用异常。

The human CCDC53 protein, a key subunit of the WASH (Wiskott-Aldrich syndrome protein and SCAR homologue) complex, plays a critical role in regulating actin cytoskeleton dynamics and membrane trafficking. The WASH complex, composed of WASH1. FAM21. SWIP, Strumpellin, and CCDC53. facilitates actin nucleation through Arp2/3-mediated branching, particularly at endosomal membranes. CCDC53. characterized by its coiled-coil domains, serves as a structural scaffold, stabilizing interactions among subunits and anchoring the complex to vesicles. It is essential for endosomal sorting, receptor recycling, and lysosomal degradation, impacting cellular processes like autophagy, cell signaling, and organelle morphology. Dysregulation of the WASH complex or its subunits has been linked to neurodevelopmental disorders, cancers, and hereditary spastic paraplegias (HSPs). Studies suggest CCDC53 mutations may disrupt vesicle trafficking, contributing to pathological axon degeneration in HSP. Recombinant CCDC53 proteins, generated via heterologous expression systems, are widely used to study WASH complex assembly, actin network regulation, and disease mechanisms. Ongoing research aims to elucidate its post-translational modifications and interactions with trafficking adaptors, which may inform therapeutic strategies targeting vesicular transport disorders.
