FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Protein geranylgeranyltransferase type I (GGTase-I) transfers a geranylgeranyl group to the cysteine residue of candidate proteins containing a C-terminal CAAX motif in which 'A' is an aliphatic amino acid and 'X' is leucine (summarized by Zhang et al., 1994 [PubMed 8106351]). The enzyme is composed of a 48-kD alpha subunit (FNTA; MIM 134635) and a 43-kD beta subunit, encoded by the PGGT1B gene. The FNTA gene encodes the alpha subunit for both GGTase-I and the related enzyme farnesyltransferase.[supplied by OMIM, Mar 2010]
PHENOTYPE: Homozygous inactivation of this gene blocks proliferation of primary mouse fibroblasts, disrupts the actin cytoskeleton, and results in altered cell morphology and reduced cell migration in a standard wound healing assay. [provided by MGI curators]
