MGI Phenotype Strain: 5428754
Lethality: E10-E11
FUNCTION: 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. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2015]
PHENOTYPE: Mice homozygous for a knock-out allele die around E11 exhibiting pallor, embryonic growth arrest, yolk sac and placental abnormalities, and an endothelial cell-autonomous defect in sprouting angiogenesis. Knock-in mice homozygous for a point mutation display similar angiogenesis defects. [provided by MGI curators]

Protein Function and Prediction

ARAP3 (alternatively, centaurin, delata-3 (Centd3)) is a PtdIns(3,4,5)P3 binding protein.  ARAP3 is a PtdIns(3,4,5)P3/PtdIns(3,4)P2-stimulated Arf6 GAP and a Rap-activated RhoA GAP that mediates PI3K-dependent rearrangements in the cell cytoskeleton and cell shape (1;2).  Gambardella et al. determined that ARAP3 is essential for developmental angiogenesis (3).  Further studies found that ARAP3 regulates chemotaxis and adhesion-dependent processes in neutrophils (4). Furthermore, it has been shown that ARAP3 is essential for growth factor-stimulated formation of lamellipodia in an endothelial cell model (5).

Background

Arap3tm1.2Sve/tm1.2Sve; MGI:5428754

involves: 129P2/OlaHsd * BALB/cJ * C57BL/6 * SJL

Homozygotes of this targeted knockout model die around E11.  This deletion results in abnormal placenta vasculature, decreased embryo size, wrinkled and pale yolk sac, abnormal brain vasculature, abnormal angiogenesis, and abnormal vascular remodeling during development (3).
