RRD1/YIL153W Summary Help

Standard Name RRD1 1 (see Nomenclature conflict Note)
Systematic Name YIL153W
Alias YPA1
Feature Type ORF, Verified
Description Peptidyl-prolyl cis/trans-isomerase; activator of the phosphotyrosyl phosphatase activity of PP2A; involved in G1 phase progression, microtubule dynamics, bud morphogenesis and DNA repair; required for rapid reduction of Sgs1p levels in response to rapamycin; subunit of the Tap42p-Sit4p-Rrd1p complex; protein increases in abundance and relative distribution to the nucleus increases upon DNA replication stress (1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11)
Name Description Resistant to Rapamycin Deletion 1
