WDR45(WD Repeat Domain 45)是一种编码WD40重复蛋白的基因,属于WIPI(WD-repeat protein Interacting with PhosphoInositides)基因家族。该家族成员通常参与自噬过程,通过结合磷脂酰肌醇(如PI3P)调控自噬体的形成。WDR45蛋白在自噬中发挥关键作用,帮助细胞清除受损的蛋白质和细胞器,维持细胞内稳态。WDR45主要在神经系统中高表达,其功能异常与神经退行性疾病密切相关。WDR45突变会导致β-螺旋桨蛋白相关神经退行性疾病(BPAN),这是一种罕见的神经发育障碍,表现为智力障碍、癫痫、运动障碍和铁沉积引起的神经变性。WDR45突变通常导致功能丧失,影响自噬过程,导致细胞内废物积累和神经元损伤。WDR45过表达可能增强自噬活性,有助于清除异常蛋白聚集,但过度自噬也可能导致细胞死亡。相反,WDR45表达降低会损害自噬功能,导致神经退行性变和铁代谢异常。WDR45与其他自噬相关基因(如ATG2、ATG9)相互作用,共同调控自噬体的形成和成熟。WIPI家族成员的共性是含有WD40重复结构域,能够识别磷脂酰肌醇并参与膜运输和自噬过程。WDR45的功能研究为理解神经退行性疾病的机制提供了重要线索,并可能成为治疗靶点。
This gene encodes a member of the WD repeat protein family. WD repeats are minimally conserved regions of approximately 40 amino acids typically bracketed by gly-his and trp-asp (GH-WD), which may facilitate formation of heterotrimeric or multiprotein complexes. Members of this family are involved in a variety of cellular processes, including cell cycle progression, signal transduction, apoptosis, and gene regulation. This gene has a pseudogene at chromosome 4q31.3. Multiple alternatively spliced transcript variants encoding distinct isoforms have been found for this gene, but the biological validity and full-length nature of some variants have not been determined.
