Protein farnesyltransferase/geranylgeranyltransferase type-1 subunit alpha

UniProtKB accession:  Q04631

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Essential subunit of both the farnesyltransferase and the geranylgeranyltransferase complex. Contributes to the transfer of a farnesyl or geranylgeranyl moiety from farnesyl or geranylgeranyl diphosphate to a cysteine at the fourth position from the C-terminus of several proteins having the C-terminal sequence Cys-aliphatic-aliphatic-X. May positively regulate neuromuscular junction development downstream of MUSK via its function in RAC1 prenylation and activation.
