Binding of APC may activate RAC1 GEF activity. The APC-ARHGEF4 complex seems to be involved in cell migration as well as in E-cadherin-mediated cell-cell adhesion. Required for MMP9 up-regulation via the JNK signaling pathway in colorectal tumor cells. Involved in tumor angiogenesis and may play a role in intestinal adenoma formation and tumor progression. {ECO:0000269|PubMed:10947987, ECO:0000269|PubMed:12598901, ECO:0000269|PubMed:17145773, ECO:0000269|PubMed:17599059, ECO:0000269|PubMed:19893577}. |RhoGEF| |SH3 1| |SH3 2| |PH| |filopodium assembly| |Rac guanyl-nucleotide exchange factor activity| |lamellipodium assembly| |lamellipodium organization| |ruffle membrane| |guanyl-nucleotide exchange factor activity| |regulation of Rho protein signal transduction| |regulation of Ras protein signal transduction| |protein domain specific binding| |regulation of small GTPase mediated signal transduction| |plasma membrane bounded cell projection assembly| |cell projection assembly| |positive regulation of apoptotic process| |positive regulation of programmed cell death| |positive regulation of cell death| |plasma membrane bounded cell projection organization| |cell projection organization| |G protein-coupled receptor signaling pathway| |regulation of apoptotic process| |regulation of programmed cell death| |regulation of cell death| |intracellular signal transduction| |regulation of intracellular signal transduction| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp277|Curcumin 6.5μM R06 exp277]]|-1.89| |[[:results:exp289|Hydroxyurea 15μM R06 exp289]]|-1.84| |[[:results:exp374|Latrunculin-B 10μM R07 exp374]]|1.76| |[[:results:exp90|WYE-354 6μM R02 exp90]]|2.31| No correlation found to any other genes in chemogenomics.
