This protein , designated p532 based on its predicted molecular weight ( EMBO J 15 : 5738 , 1996 ) , contains multiple structural domains including two regions of seven internal repeats highly related to the cell cycle regulator RCC1 , a guanine nucleotide exchange factor for the small GTP - binding protein Ran , seven beta - repeat domains characteristic of the beta subunit of heterotrimeric G proteins , three putative SH3 binding sites , a putative leucine - zipper and a carboxy - terminal HECT domain characteristic of E3 ubiquitin - protein ligases .
