UGO1/YDR470C Summary Help

Standard Name UGO1 1
Systematic Name YDR470C
Feature Type ORF, Verified
Description Outer membrane component of the mitochondrial fusion machinery; binds directly to Fzo1p and Mgm1p and thus links these two GTPases during mitochondrial fusion; involved in fusion of both the outer and inner membranes; facilitates dimerization of Fzo1p during fusion; import into the outer membrane is mediated by Tom70p and Mim1p; has similarity to carrier proteins but is not likely to function as a transmembrane transporter (1, 2, 3, 4, 5, 6, 7)
Name Description UGO (Japanese for fusion) 1
