该基因位于2号染色体上的一组ran结合蛋白相关基因中，该基因在灵长类动物中通过复制产生。编码的蛋白质包含一个N端TPR（四肽重复序列）结构域、两个RAN结合结构域和一个C端GRIP结构域（Golgin-97、Ranbp2Alpha、IMH1P和P230/Golgin-245）。[由RefSeq提供，2011年9月]
This gene is located in a cluster of Ran-binding protein related genes on chromosome 2 which arose through duplication in primates. The encoded protein contains an N-terminal TPR (tetratricopeptide repeat) domain, two Ran-binding domains, and a C-terminal GRIP domain (golgin-97, RanBP2alpha, Imh1p and p230/golgin-245) domain.
