PHB2/YGR231C Summary Help

Standard Name PHB2
Systematic Name YGR231C
Feature Type ORF, Verified
Description Subunit of the prohibitin complex (Phb1p-Phb2p); prohibitin is a 1.2 MDa ring-shaped inner mitochondrial membrane chaperone that stabilizes newly synthesized proteins; determinant of replicative life span; involved in mitochondrial segregation; prohibitin deficiency induces a mitochondrial unfolded protein response (mtUPR) (1, 2, 3, 4, 5, 6)
Name Description ProHiBitin
