Summaries for GDI1 Gene

Entrez Gene Summary for GDI1 Gene

  • GDP dissociation inhibitors are proteins that regulate the GDP-GTP exchange reaction of members of the rab family, small GTP-binding proteins of the ras superfamily, that are involved in vesicular trafficking of molecules between cellular organelles. GDIs slow the rate of dissociation of GDP from rab proteins and release GDP from membrane-bound rabs. GDI1 is expressed primarily in neural and sensory tissues. Mutations in GDI1 have been linked to X-linked nonspecific mental retardation. [provided by RefSeq, Jul 2008]

GeneCards Summary for GDI1 Gene

GDI1 (GDP Dissociation Inhibitor 1) is a Protein Coding gene. Diseases associated with GDI1 include tumor of exocrine pancreas and mental retardation. Among its related pathways are Signaling by GPCR and Rho GTPase cycle. GO annotations related to this gene include GTPase activator activity and GDP-dissociation inhibitor activity. An important paralog of this gene is CHML.

UniProtKB/Swiss-Prot for GDI1 Gene

  • Regulates the GDP/GTP exchange reaction of most Rab proteins by inhibiting the dissociation of GDP from them, and the subsequent binding of GTP to them. Promotes the dissociation of GDP-bound Rab proteins from the membrane and inhibits their activation. Promotes the dissociation of RAB1A, RAB3A, RAB5A and RAB10 from membranes.
