Gene: GDI1 (GDP dissociation inhibitor 1) Homo sapiens
Symbol: GDI1
Name: GDP dissociation inhibitor 1
Description: Predicted to have Rab GDP-dissociation inhibitor activity and Rab GTPase binding activity. Involved in negative regulation of protein targeting to membrane. Localizes to the cytoplasm and midbody. Implicated in non-syndromic X-linked intellectual disability and psychotic disorder.
Type: protein-coding
RefSeq Status: REVIEWED
