关于 KPNA3

功能概要

真核细胞中分子在细胞核和细胞质之间的运输是由核孔复合体 (NPC) 介导的，它由 60-100 种蛋白质组成。小分子 (高达 70 kD) 可以通过非选择性扩散穿过核孔，而大分子则通过活性过程运输。该基因编码的蛋白属于 importin alpha 家族，参与核蛋白导入。[RefSeq 提供，2009 年 1 月]

The transport of molecules between the nucleus and the cytoplasm in eukaryotic cells is mediated by the nuclear pore complex (NPC), which consists of 60-100 proteins. Small molecules (up to 70 kD) can pass through the nuclear pore by nonselective diffusion while larger molecules are transported by an active process. The protein encoded by this gene belongs to the importin alpha family, and is involved in nuclear protein import. [provided by RefSeq, Jan 2009]
