CST9

Gene
CST9
Protein
Chromosome stability protein 9
Organism
Saccharomyces cerevisiae (strain ATCC 204508 / S288c)
Length
482 amino acids
Function
Component of the synapsis initiation complex (SIC) necessary for the synaptonemal complex assembly. Stabilizes the ZIP2 component to the chromosomes. The SIC complex loads onto chromosomes and nucleates ZIP1 polymerization, a molecular zipper that acts to bring homologous chromosomes in close apposition, which is required for meiotic crossover. May also be involved in double strand break repair.
