GOLPH3 is the first example of a Golgi resident oncogene protein. It was independently identified in multiple screens; first in proteomic-based screens as a resident protein of the Golgi apparatus, and second as an oncogene product in a screen for genes amplified in cancer. A third screen uncovered the association of GOLPH3 with the Golgi resident phospholipid, phosphatidyl inositol 4 phosphate (PI4P) to maintain the characteristic ribbon structure of the Golgi apparatus favoring vesicular transport of secretory proteins.
GOLPH3 是第一个被鉴定的定位于高尔基体的致癌基因蛋白。它是通过多种筛选方法独立鉴定出来的:首先在基于蛋白质组学的筛选中,它被鉴定为高尔基体的固有蛋白,其次在筛选扩增的癌基因产物中,它被鉴定为致癌基因蛋白。第三次筛选揭示了 GOLPH3 与高尔基体驻留磷脂酰肌醇 4 磷酸(PI4P)的关联,以维持高尔基体的特征带状结构,有利于分泌蛋白的囊泡运输。
