Also known as: GAPIII; GAP1IP4BP
Summary: This gene encodes a protein that binds inositol 1,3,4,5-tetrakisphosphate and stimulates the GTPase activity of Ras p21. This protein functions as a negative regulator of the Ras signalling pathway. It is localized to the cell membrane via a pleckstrin homology (PH) domain in the C-terminal region. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Mar 2016]

What's a GeneRIF?

Rasa3 is a critical regulator of Rap1 in endothelial cells which controls adhesions properties and vascular lumen integrity; its specific endothelial cell inactivation results in occluded blood vessels, hemorrhages and early embryonic death in mouse, mimicking thus the Rasa3-/- mouse phenotype.
Title: Rasa3 controls turnover of endothelial cell adhesion and vascular lumen integrity by a Rap1-dependent mechanism.
these results support an important role for Rasa3 in PI3K-dependent integrin alphaIIbbeta3-mediated outside-in signaling and cell spreading.
Title: The Phosphatidylinositol 3,4,5-trisphosphate (PI(3,4,5)P3) Binder Rasa3 Regulates Phosphoinositide 3-kinase (PI3K)-dependent Integrin αIIbβ3 Outside-in Signaling.
the function of RASA3 during megakaryopoiesis, megakaryocyte adhesion and migration as well as integrin signaling has been reported.
Title: The Ras/Rap GTPase activating protein RASA3: from gene structure to in vivo functions.
model in which the Ras GAP-related domain of GAP1(IP4BP) functions to stabilize the switch II region of Rap1, allowing stabilization of the transition state during GTP hydrolysis initiated by the arginine finger
Title: The ability of GAP1IP4BP to function as a Rap1 GTPase-activating protein (GAP) requires its Ras GAP-related domain and an arginine finger rather than an asparagine thumb.
role in intracellular calcium homeostasis
Title: Analyzing the role of the putative inositol 1,3,4,5-tetrakisphosphate receptor GAP1IP4BP in intracellular Ca2+ homeostasis.
GAP1IP4BP is an inositol 1,3,4,5-tetrakisphosphate regulated plasma membrane associated Ras and Rap GAP. Membrane association results from its PH domain binding phosphatidylinositol 4,5-bisphosphate.
Title: Identification of a specific Ins(1,3,4,5)P4-binding protein as a member of the GAP1 family.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
