Feature type ORF, Verified
Coordinates Chr III:22106..18816

Description of YCL061C: S-phase checkpoint protein required for DNA replication; interacts with and stabilizes Pol2p at stalled replication forks during stress, where it forms a pausing complex with Tof1p and is phosphorylated by Mec1p; protects uncapped telomeres[1][2][3][4]

Specifically higher expression in nitrogen limited chemostat cultures versus nitrogen excess. [5] [6]


The MRC1 deletion in the systematic deletion collection uses a start codon 3' of the real start codon. Thus, it truncates and DAmPs the gene rather than deleting it.
