Human Gene PGGT1B (uc003kqw.4) Description and Page Index
  Description: Homo sapiens protein geranylgeranyltransferase type I, beta subunit (PGGT1B), mRNA.
RefSeq Summary (NM_005023): 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]. Sequence Note: This RefSeq record was created from transcript and genomic sequence data because no single transcript was available for the full length of the gene. The extent of this transcript is supported by transcript alignments. Publication Note: This RefSeq record includes a subset of the publications that are available for this gene.

DESCRIPTION: RecName: Full=Geranylgeranyl transferase type-1 subunit beta; EC=; AltName: Full=Geranylgeranyl transferase type I subunit beta; Short=GGTase-I-beta; AltName: Full=Type I protein geranyl-geranyltransferase subunit beta;
FUNCTION: Catalyzes the transfer of a geranyl-geranyl moiety from geranyl-geranyl pyrophosphate to a cysteine at the fourth position from the C-terminus of proteins having the C-terminal sequence Cys-aliphatic-aliphatic-X. Acts on the Rac1, Rac2, Rap1A and Rap1B proteins. The beta subunit is responsible for peptide-binding.
CATALYTIC ACTIVITY: Geranylgeranyl diphosphate + protein-cysteine = S-geranylgeranyl-protein + diphosphate.
COFACTOR: Binds 1 zinc ion per subunit (By similarity).
SUBUNIT: Heterodimer of an alpha and a beta subunit.
SIMILARITY: Belongs to the protein prenyltransferase subunit beta family.
SIMILARITY: Contains 4 PFTB repeats.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.

-  Orthologous Genes in Other Species
  Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
