MIM1/YOL026C Summary Help

Standard Name MIM1 1
Systematic Name YOL026C
Alias TOM13 2
Feature Type ORF, Verified
Description Mitochondrial protein required for outer membrane protein import; cooperates with Tom70p to import the subset of proteins with multiple alpha-helical transmembrane segments, including Ugo1p, Tom20p, and others; present in a complex with Mim2p in the outer membrane that may create a local environment to facilitate membrane insertion of substrate proteins; also has a role in assembly of Tom20p into the TOM complex (1, 2, 3, 4, 5, 6, 7, 8)
