Dynein heavy chain, cytoplasmic; Cytoplasmic dynein acts as a motor for the intracellular retrograde motility of vesicles and organelles along microtubules. Dynein has ATPase activity; the force-producing power stroke is thought to occur on release of ADP. Required for nuclear movement during meiotic prophase.

Kinesin-like protein cut7; Could be a spindle pole body motor. On transition from G2 to M phase of the cell cycle, the spindle pole body duplicates; the daughter pole bodies seed microtubules which interdigitate to form a short spindle that elongates to span the nucleus at metaphase. Mutations at cut7 block spindle formation.

Microtubule integrity protein mal3; May play a role in regulating the integrity of microtubules possibly by influencing their stability. Involved in an anchoring mechanism to maintain tea2 and tip1 at growing microtubule ends. Strongly stimulates the ATPase activity of tea2. Belongs to the MAPRE family.

Dynein intermediate chain 1; Has a role in meiotic nuclear divsion where it promotes the movement of 'horsetails'; Belongs to the dynein intermediate chain family.

Inner kinetochore subunit mis6; Component of the kinetochore, a multiprotein complex that assembles on centromeric DNA and attaches chromosomes to spindle microtubules, mediating chromosome segregation and sister chromatid segregation during meiosis and mitosis. Component of the inner kinetochore constitutive centromere-associated network (CCAN), which serves as a structural platform for outer kinetochore assembly. Required for the localization of cnp1 to the centromere ; Belongs to the CENP-I/CTF3 family.

Tubulin alpha-1 chain; Tubulin is the major constituent of microtubules. It binds two moles of GTP, one at an exchangeable site on the beta chain and one at a non-exchangeable site on the alpha chain.

Actin; Actins are highly conserved proteins that are involved in various types of cell motility and are ubiquitously expressed in all eukaryotic cells.

Spindle pole body component alp14; Required for bipolar spindle formation and proper chromosome segregation. Has a role in connecting the kinetochores and the plus end of pole to chromosome microtubules. Also required for the activation of the spindle checkpoint pathway; Belongs to the TOG/XMAP215 family.

Nuclear envelope protein ndc1; Component of the nuclear pore complex (NPC) and the spindle pole body (SPB), which plays a key role in de novo assembly and insertion of both structures in the nuclear envelope. Involved in the formation of the bipolar mitotic spindle. Anchors the spindle pole body in the nuclear envelope; Belongs to the NDC1 family.
