Rho GTPase activating proteins act by converting Rho-type GTPases to an inactive GDP-bound state (PubMed:21865595). Plays a key role in tissue tension and 3D tissue shape by regulating cortical actomyosin network formation. Acts downstream of YAP1 and inhibits actin polymerization, which in turn reduces nuclear localization of YAP1 (PubMed:25778702). Regulates cell shape, spreading, and migration (PubMed:21865595). {ECO:0000269|PubMed:21865595, ECO:0000269|PubMed:25778702}. |RhoGAP| |regulation of cell shape| |regulation of actin filament polymerization| |regulation of actin polymerization or depolymerization| |regulation of actin filament length| |regulation of protein polymerization| |regulation of actin filament organization| |GTPase activator activity| |cadherin binding| |small GTPase mediated signal transduction| |regulation of actin cytoskeleton organization| |regulation of small GTPase mediated signal transduction| |regulation of supramolecular fiber organization| |regulation of cellular component size| |regulation of actin filament-based process| |nuclear speck| |positive regulation of GTPase activity| |regulation of protein complex assembly| |regulation of GTPase activity| |regulation of cell morphogenesis| |regulation of anatomical structure size| |regulation of cytoskeleton organization| |positive regulation of hydrolase activity| |regulation of cell motility| |regulation of cellular component biogenesis| |regulation of locomotion| |regulation of cellular component movement| |regulation of anatomical structure morphogenesis| |regulation of hydrolase activity| |regulation of organelle organization| |positive regulation of catalytic activity| |intracellular signal transduction| |positive regulation of molecular function| |regulation of intracellular signal transduction| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp340|BN82002 4μM R07 exp340]]|1.79| |[[:results:exp497|Lead acetate 2000μM R08 exp497]]|1.98| ^Gene^Correlation^ |[[:human genes:h:hgc6.3|HGC6.3]]|0.555| Global Fraction of Cell Lines Where Essential: 0/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|0/1| |909776.0|0/1| |bile duct|0/28| |blood|0/28| |bone|0/26| |breast|0/33| |central nervous system|0/56| |cervix|0/4| |colorectal|0/17| |esophagus|0/13| |fibroblast|0/1| |gastric|0/16| |kidney|0/21| |liver|0/20| |lung|0/75| |lymphocyte|0/16| |ovary|0/26| |pancreas|0/24| |peripheral nervous system|0/16| |plasma cell|0/15| |prostate|0/1| |skin|0/24| |soft tissue|0/9| |thyroid|0/2| |upper aerodigestive|0/22| |urinary tract|0/29| |uterus|0/5| == Essentiality in NALM6 == * **Essentiality Rank**: 16434 * **Expression level (log2 read counts)**: 3.59 {{:chemogenomics:nalm6 dist.png?nolink |}}
