属于肌动蛋白结合蛋白的profilin家族的蛋白质被认为是肌动蛋白聚合的重要控制元件,并且已经与广谱的细胞功能(包括细胞迁移)相关联。最近发表在《癌细胞》上的一篇有趣的论文揭示了profilin-1和profilin-2(profilin的两种主要亚型)对肌动蛋白细胞骨架调节、运动性和乳腺癌细胞侵袭的不同作用,并进一步建立了profilin-2对乳腺癌细胞迁移抑制作用的机制。这种观点讨论了这些发现的意义,在如何profilins可能调节乳腺癌细胞的运动。
Proteins belonging to the profilin family of actin-binding proteins are considered to be important control elements for actin polymerization and have been linked to a broad spectrum of cellular functions, including cell migration. An intriguing paper recently published in Cancer Cell unveils differential effects of profilin-1 and profilin-2, the two major isoforms of profilin, on actin cytoskeletal regulation, motility, and invasion of breast cancer cells, and further establishes a mechanism underlying profilin-2's suppressive effect on breast cancer cell migration. This viewpoint discusses the implications of these findings in the context of how profilins might regulate breast cancer cell motility.
