Gene Gene information from NCBI Gene database.
Entrez ID 23229
Gene name Cdc42 guanine nucleotide exchange factor 9
Gene symbol ARHGEF9
Synonyms (NCBI Gene)
COLLYBISTINDEE8EIEE8HPEM-2PEM-2PEM2
Chromosome X
Chromosome location Xq11.1
Summary The protein encoded by this gene is a Rho-like GTPase that switches between the active (GTP-bound) state and inactive (GDP-bound) state to regulate CDC42 and other genes. This brain-specific protein also acts as an adaptor protein for the recruitment of g
