PCM1(Pericentriolar Material 1)基因编码一种重要的中心粒周围基质蛋白,主要定位于中心粒周围区域,参与中心体的组装和功能维持。它在细胞分裂过程中发挥关键作用,确保纺锤体的正确形成和染色体的精确分离。PCM1蛋白通过与多种其他中心体蛋白(如CEP290、BBS4)相互作用,维持微管组织中心的稳定性,并参与纤毛的形成和功能。PCM1的突变可能导致纤毛功能障碍,与多种纤毛病(如Bardet-Biedl综合征、Joubert综合征)相关,表现为视网膜退化、肾脏异常和神经发育缺陷等。PCM1过表达可能干扰中心体的正常功能,导致非整倍体或染色体不稳定,增加癌症风险;而表达降低则可能引起纤毛结构异常,影响细胞信号传导和器官发育。PCM1属于中心粒周围基质蛋白家族,该家族成员通常参与中心体/纤毛相关功能,具有维持微管组织、细胞分裂和细胞极性调控等共性。此外,PCM1还与精神分裂症等神经精神疾病存在潜在关联,可能通过影响神经元迁移和突触功能参与发病机制。
The protein encoded by this gene is a component of centriolar satellites, which are electron dense granules scattered around centrosomes. Inhibition studies show that this protein is essential for the correct localization of several centrosomal proteins, and for anchoring microtubules to the centrosome. Chromosomal aberrations involving this gene are associated with papillary thyroid carcinomas and a variety of hematological malignancies, including atypical chronic myeloid leukemia and T-cell lymphoma.
