FunFam 11: mitochondrial import receptor subunit TOM40 homolo...

Please note: GO annotations are assigned to the full protein sequence rather than individual protein domains. Since a given protein can contain multiple domains, it is possible that some of the annotations below come from additional domains that occur in the same protein, but have been classified elsewhere in CATH.

There are 7 GO terms relating to "molecular function"
