syp-2 encodes a coiled-coil protein; during meiosis, syp-2 activity is required for the normal progression of chromosome organization in the nucleus, for maintaining stable pairing between homologous chromosomes subsequent to initial pairing, and for productive crossover events and chiasmata formation; SYP-2 localizes to the region between paired homologous chromosomes during pachytene and disappears from this interface by late diakinesis, suggesting that SYP-2 is a structural component of the central element of the synaptonemal complex (SC); SYP-2 localization to the SC is dependent upon activity of HIM-3 and REC-8, meiosis-specific axis components, while SYP-1, an additional SC component, and SYP-2 are interdependent for localization to the SC.
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
