3fwb is a 3 chain structure with sequence from Saccharomyces cerevisiae. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
CDC31_YEAST Functions as a component of the nuclear pore complex (NPC) and the spindle pole body (SPB) half-bridge. At the SPB, it is recruited by KAR1 and MPS3 to the SPB half-bridge and involved in the initial steps of SPB duplication. It probably plays a similar role in de novo assembly of NPCs at the nuclear envelope. Also involved in connection with the protein kinase KIC1 in the maintenance of cell morphology and integrity.[1][2][3][4][5][6]
