这个基因编码一个大蛋白，作为一个gdp到gtp的交换因子。这种蛋白质促进肌动蛋白细胞骨架的重组，从而在细胞迁移和生长中发挥作用。选择性剪接导致多个转录变体[由RefSeq提供，2015年12月]
This gene encodes a large protein that functions as a GDP to GTP exchange factor. This protein promotes the reorganization of the actin cytoskeleton, thereby playing a role in cell migration and growth. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2015]
