IQ motif and Sec7 domain 2 is a protein that in humans is encoded by the IQSEC2 gene.^[5]^[6]

Function

The IQSEC2 gene encodes a guanine nucleotide exchange factor for the ARF family of GTP-binding proteins (see for example ARF1).^[7]

Clinical significance

It is associated with X-Linked mental retardation 1.^[7]
