Feature type ORF, Verified
Coordinates Chr X:257423..260947
Primary SGDID S000003628

Description of YJL092W: DNA helicase and DNA-dependent ATPase involved in DNA repair and checkpoint recovery, needed for proper timing of commitment to meiotic recombination and transition from Meiosis I to II; blocks trinucleotide repeat expansion; affects genome stability[1][2][3][4][5][6][7][8]
