Protein: Spindle pole body-associated protein CIK1 (Chromosome instability and karyogamy protein 1) (Q01649)
Organism: Saccharomyces cerevisiae (strain ATCC 204508 / S288c) (Baker's yeast)
Function: A developmentally regulated protein important for microtubule functions. Targets KAR3 to the cytoplasmic microtubules during mating. Essential for KAR3 function during prophase of meiosis I. Required for interhomolog recombination, synapsis of homologous chromosomes and establishment of a meiosis I spindle.
Subcellular location: Nucleus {ECO:0000269|PubMed:11729143}. Cytoplasm, cytoskeleton, microtubule organizing center, spindle pole body {ECO:0000269|PubMed:11729143}. Cytoplasm, cytoskeleton, spindle {ECO:0000269|PubMed:11729143, ECO:0000269|PubMed:25313961}. Cytoplasm, cytoskeleton {ECO:0000269|PubMed:8106549}. Note=Localization to the spindle pole body is infrequent in meiotic cells (PubMed:11729143). Localizes to cytoplasmic microtubules during mating (PubMed:8106549). {ECO:0000269|PubMed:11729143, ECO:0000269|PubMed:8106549}.
