Human Gene GEM (ENST00000396194.6) Description and Page Index
  Description: Homo sapiens GTP binding protein overexpressed in skeletal muscle (GEM), transcript variant 2, mRNA. (from RefSeq NM_181702)
RefSeq Summary (NM_181702): The protein encoded by this gene belongs to the RAD/GEM family of GTP-binding proteins. It is associated with the inner face of the plasma membrane and could play a role as a regulatory protein in receptor-mediated signal transduction. Alternative splicing occurs at this locus and two transcript variants encoding the same protein have been identified. [provided by RefSeq, Jul 2008].

DESCRIPTION: RecName: Full=GTP-binding protein GEM; AltName: Full=GTP-binding mitogen-induced T-cell protein; AltName: Full=RAS-like protein KIR;
FUNCTION: Could be a regulatory protein, possibly participating in receptor-mediated signal transduction at the plasma membrane. Has guanine nucleotide-binding activity but undetectable intrinsic GTPase activity.
SUBUNIT: Interacts with calmodulin in a Ca(2+)-dependent manner. Binds ROCK1.
INTERACTION: P36406:TRIM23; NbExp=3; IntAct=EBI-744104, EBI-740098;
SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein; Cytoplasmic side.
TISSUE SPECIFICITY: Most abundant in thymus, spleen, kidney, lung, and testis. Less abundant in heart, brain, liver and skeletal muscle.
INDUCTION: By mitogens.
PTM: Phosphorylated on tyrosine residues.
SIMILARITY: Belongs to the small GTPase superfamily. RGK family.

ModBase Predicted Comparative 3D Structure on P55040
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.
