Basic Information

NameMitochondrial import receptor subunit TOM40 (Mitochondrial import site protein ISP42) (Translocase of outer membrane 40 kDa subunit)
Uniprot IDP23644
Systematic gene nameYMR203W
Standard gene nameTOM40
Gene namesTOM40 ISP42 MOM38 YMR203W YM8325.04
Description from SGDYMR203W TOM40 SGDID:S000004816, Chr XIII from 668492-669655, Genome Release 64-3-1, Verified ORF, "Component of the TOM (translocase of outer membrane) complex; responsible for recognition and initial import steps for all mitochondrially directed proteins; constitutes the core element of the protein conducting pore; pre-Tom40p is phosphorylated by PKA, which impairs its import into mitochondria under non-respiratory conditions"
