SAE2/YGL175C Summary Help

Standard Name SAE2 1
Systematic Name YGL175C
Alias COM1 2
Feature Type ORF, Verified
Description Endonuclease required for telomere elongation; also required for telomeric 5' C-rich strand resection; involved in processing hairpin DNA structures with MRX complex; involved in double-strand break repair; required for normal resistance to DNA-damaging agents; exists in form of inactive oligomers that are transiently released into smaller active units by a series of phosphorylations; DNA damage triggers removal of Sae2p ensuring that active Sae2p is present only transiently (1, 2, 3, 4, 5, 6, 7)
Name Description Sporulation in the Absence of spo Eleven 1
