PST2/YDR032C Summary Help

Standard Name PST2 1
Systematic Name YDR032C
Feature Type ORF, Verified
Description Protein with similarity to a family of flavodoxin-like proteins; induced by oxidative stress in a Yap1p dependent manner; the authentic, non-tagged protein is detected in highly purified mitochondria in high-throughput studies; protein abundance increases in response to DNA replication stress; PST2 has a paralog, RFS1, that arose from the whole genome duplication (2, 3, 4, 5, 6, 7, 8)
Name Description Protoplasts-SecreTed 9
