Encodes a subunit of the delta DNA polymerase II.
mutant is hypomorphic, since null mutant is lethal. [Iglesias et al., 2015] Remarks: gis5
single mutant has more H3K4me3 activating marks at the SEP3
locus when grown at higher temperature (24C vs 18C). [Iglesias et al., 2015] Single mutant: gis5
single mutant is early flowering under both SD and LD conditions. (Under SD conditions, the late-flowering phenotype is stronger at 24C than 18C.) [Iglesias et al., 2015] Remarks: gis5
single mutant is thermosensistive, has pleiotropic defects, and is unable to complete a full developmental cycle when grown at 28C. [Iglesias et al., 2015] Function:
This polymerase possesses two enzymatic activities: DNA synthesis (polymerase) and an exonucleolytic activity that degrades single-stranded DNA in the 3 - to 5 -direction. [Data from UniProt]
