Summaries for FGD1 Gene

Entrez Gene Summary for FGD1 Gene

  • This gene encodes a protein that contains Dbl (DH) and pleckstrin (PH) homology domains and is similar to the Rho family of small GTP-binding proteins. The encoded protein specifically binds to the Rho family GTPase Cdc42Hs and can stimulate the GDP-GTP exchange of the isoprenylated form of Cdc42Hs. It also stimulates the mitogen activated protein kinase cascade leading to c-Jun kinase SAPK/JNK1 activation. Defects in this gene are the cause of faciogenital dysplasia and X-linked mental retardation, syndromatic 16.[provided by RefSeq, Mar 2011]

GeneCards Summary for FGD1 Gene

FGD1 (FYVE, RhoGEF And PH Domain Containing 1) is a Protein Coding gene. Diseases associated with FGD1 include Aarskog-Scott Syndrome and Fgd1-Related X-Linked Mental Retardation. Among its related pathways are p75 NTR receptor-mediated signalling and G-protein signaling_Regulation of CDC42 activity. GO annotations related to this gene include guanyl-nucleotide exchange factor activity and small GTPase binding. An important paralog of this gene is FGD4.

UniProtKB/Swiss-Prot for FGD1 Gene

  • Activates CDC42, a member of the Ras-like family of Rho- and Rac proteins, by exchanging bound GDP for free GTP. Plays a role in regulating the actin cytoskeleton and cell shape.
