细胞生长根据外部线索(例如营养物质可用性、生长因子信号和压力)进行动态调节。这一适应过程的核心是雷帕霉素复合物 1 (TORC1) 的靶标,这是一种进化上保守的激酶复合物,可微调大量细胞事件。上游信号如何被感知并传输至 TORC1 已在包括芽殖酵母酿酒酵母在内的主要模型生物中进行了深入研究。该领域最近取得了突破:鉴定出酵母磷脂酰肌醇(3)-磷酸结合蛋白 2 (Pib2) 蛋白作为 TORC1 的关键调节因子。尽管对 Pib2 的研究仍处于早期阶段,但多个研究小组已经就 Pib2 如何将营养信号传递给 TORC1 提供了重要的机制见解。另一方面,我们的知识和谜团仍然存在重大差距,需要进一步调查。这是对 Pib2 的首次专门综述,总结了有关细胞生长调节中这一新兴关键角色的主要发现和突出问题。
Cell growth is dynamically regulated in response to external cues such as nutrient availability, growth factor signals, and stresses. Central to this adaptation process is the Target of Rapamycin Complex 1 (TORC1), an evolutionarily conserved kinase complex that fine-tunes an enormous number of cellular events. How upstream signals are sensed and transmitted to TORC1 has been intensively studied in major model organisms including the budding yeast Saccharomyces cerevisiae. This field recently saw a breakthrough: the identification of yeast phosphatidylInositol(3)-phosphate binding protein 2 (Pib2) protein as a critical regulator of TORC1. Although the study of Pib2 is still in its early days, multiple groups have provided important mechanistic insights on how Pib2 relays nutrient signals to TORC1. There remain, on the other hand, significant gaps in our knowledge and mysteries that warrant further investigations. This is the first dedicated review on Pib2 that summarizes major findings and outstanding questions around this emerging key player in cell growth regulation.
