Summary: Enables protein serine/threonine phosphatase activity. Involved in several processes, including DNA metabolic process; negative regulation of cell cycle phase transition; and positive regulation of cellular component organization. Acts upstream of or within positive regulation of exit from mitosis. Located in several cellular components, including kinetochore; mating projection base; and spindle pole body. Part of mRNA cleavage and polyadenylation specificity factor complex and protein phosphatase type 1 complex. Used to study cancer. Human ortholog(s) of this gene implicated in Noonan syndrome-like disorder with loose anagen hair 2. Orthologous to several human genes including PPP1CA (protein phosphatase 1 catalytic subunit alpha) and PPP1CC (protein phosphatase 1 catalytic subunit gamma).

We deleted the novel intronic RNA structure within the GLC7 intron and showed that this region, rather than the intron itself, is responsible for the cell's ability to respond to salt stress. We also showed a direct association between the in cis presence of the intronic RNA and GLC7 expression
Title: Novel Intronic RNA Structures Contribute to Maintenance of Phenotype in Saccharomyces cerevisiae.
These data suggest that the repression of origin activation by Rif1-Glc7 is important to avoid the deleterious accumulation of stalled replication forks at the rDNA RFB, which become lethal when fork stability is compromised. Finally, we show that Rif1-Glc7, unlike Sir2, has an important effect on origin firing outside of the rDNA locus that serves to prevent activation of the DNA replication checkpoint
