Protein

Protein farnesyltransferase subunit beta

Gene

Fntb

Organism
Mus musculus (Mouse)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Essential subunit of the farnesyltransferase complex. Catalyzes the transfer of a farnesyl moiety from farnesyl diphosphate to a cysteine at the fourth position from the C-terminus of several proteins having the C-terminal sequence Cys-aliphatic-aliphatic-X.1 Publication

Catalytic activityi

Farnesyl diphosphate + protein-cysteine = S-farnesyl protein + diphosphate.1 Publication

Cofactori

Binds 1 zinc ion per subunit.1 Publication
