Cell division control protein 31

Gene

CDC31

Organism

Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

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.6 Publications

Interactioni

Subunit structurei

The nuclear pore complex (NPC) constitutes the exclusive means of nucleocytoplasmic transport. NPCs allow the passive diffusion of ions and small molecules and the active, nuclear transport receptor-mediated bidirectional transport of macromolecules such as proteins, RNAs, ribonucleoparticles (RNPs), and ribosomal subunits across the nuclear envelope. The 55-60 MDa NPC is composed of at least 31 different subunits: ASM4, CDC31, GLE1, GLE2, NDC1, NIC96, NSP1, NUP1, NUP2, NUP100, NUP116, NUP120, NUP133, NUP145, NUP157, NUP159, NUP170, NUP188, NUP192, NUP42, NUP49, NUP53, NUP57, NUP60, NUP82, NUP84, NUP85, POM152, POM34, SEH1 and SEC1. Due to its 8-fold rotational symmetry, all subunits are present with 8 copies or multiples thereof. The spindle pole body (SPB), acting as the connector of microtubule arrays in the cytoplasm and the nucleoplasm, is involved in nuclear positioning before chromosome segregation, SPB separation, spindle formation, chromosome segregation, nuclear migration into the bud, nuclear reorientation after cytokinesis and nuclear fusion during conjugation. The SPB half-bridge, which is tightly associated with the cytoplasmic side of the nuclear envelope and the SPB, is playing a key role as the starting structure for and in the initiation of SPB duplication in G1. At the SPB half-bridge CDC31 interacts with KAR1, MPS3 and SFI1. It also interacts with KIC1.3 Publications
