IQ motif and SEC7 domain-containing protein 1 also known as ARF-GEP100 (ADP-Ribosylation Factor - Guanine nucleotide-Exchange Protein - 100-kDa) is a protein that in humans is encoded by the IQSEC1 gene.
==Function== The ARF-GEP100 protein is involved in signal transduction. It is a guanine nucleotide exchange factor that promotes binding of GTP to ADP ribosylation factor protein ARF6 and to a lesser extent ARF1 and ARF5. This activates the ADP-ribosylation activity of the target protein and cause it to modify its substrates. ARF-GEP100, through activation of ARF6, is therefore involved in the control of processes such as endocytosis of plasma membrane proteins, E-cadherin recycling and actin cytoskeleton remodeling. ARF-GEP100 appears particularly important in regulating cell adhesion, with reductions in the level of this protein causing enhanced spreading and attachment of cells.
