ArfGAP with RhoGAP domain, ankyrin repeat and PH domain 3

ARAP3, Centd3, PtdIns(3,4,5)P3-binding protein
This gene encodes a phosphoinositide binding protein containing ARF-GAP, RHO-GAP, RAS-associating, and pleckstrin homology domains. The ARF-GAP and RHO-GAP domains cooperate in mediating rearrangements in the cell cytoskeleton and cell shape. It is a specific PtdIns(3,4,5)P3/PtdIns(3,4)P2-stimulated Arf6-GAP protein. An alternatively spliced transcript has been found for this gene, but its biological validity has not been determined. [provided by RefSeq, Sep 2008] (from NCBI)

Our results indicate that antibodies obtained from our phage library that target ɛ-migis bind to a variety of human cells irrespective of mIgE expression, possibly due to homology between ɛ-migis and a region of phosphoinositide-binding protein (ARAP3).
