[[https://www.uniprot.org/uniprot/CDC31_YEAST 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.<ref>PMID:8188750</ref> <ref>PMID:8070654</ref> <ref>PMID:9813095</ref> <ref>PMID:11156974</ref> <ref>PMID:12486115</ref> <ref>PMID:14504268</ref> [[https://www.uniprot.org/uniprot/SFI1_YEAST SFI1_YEAST]] Component of the spindle pole body (SPB) half-bridge involved in the initial steps of SPB duplication.<ref>PMID:10455233</ref> <ref>PMID:14504268</ref> <ref>PMID:16785321</ref>

Centrins are calmodulin-like proteins present in centrosomes and yeast spindle pole bodies (SPBs) and have essential functions in their duplication. The Saccharomyces cerevisiae centrin, Cdc31p, binds Sfi1p on multiple conserved repeats; both proteins localize to the SPB half-bridge, where the new SPB is assembled. The crystal structures of Sfi1p-centrin complexes containing several repeats show Sfi1p as an alpha helix with centrins wrapped around each repeat and similar centrin-centrin contacts between each repeat. Electron microscopy (EM) shadowing of an Sfi1p-centrin complex with 15 Sfi1 repeats and 15 centrins bound showed filaments 60 nm long, compatible with all the Sfi1 repeats as a continuous alpha helix. Immuno-EM localization of the Sfi1p N and C termini showed Sfi1p-centrin filaments spanning the length of the half-bridge with the Sfi1p N terminus at the SPB. This suggests a model for SPB duplication where the half-bridge doubles in length by association of the Sfi1p C termini, thereby providing a new Sfi1p N terminus to initiate SPB assembly.
