Interacts with NISCH. Interacts with PIP5K1A. Interacts with the GTP-bound form of RAB7A. Interacts with SRGAP2. Interacts with CYFIP1/SRA-1. Interacts with PLXNB3. Interacts with ARHGDIA; the interaction is induced by SEMA5A, mediated through PLXNB3 and inactivates and stabilizes RAC1. Interacts (GTP-bound form preferentially) with PKN2 (via the REM repeats); the interaction stimulates autophosphorylation and phosphorylation of PKN2. Interacts with the GEF proteins PREX1, RASGRF2, FARP1, FARP2, DOCK1, DOCK2 and DOCK7, which promote the exchange between GDP and GTP, and therefore activate it. Interacts with PARD6A, PARD6B and PARD6G in a GTP-dependent manner. Part of a quaternary complex containing PARD3, some PARD6 protein (PARD6A, PARD6B or PARD6G) and some atypical PKC protein (PRKCI or PRKCZ), which plays a central role in epithelial cell polarization. Found in a trimeric complex composed of DOCK1 and ELMO1, which plays a central role in phagocytosis of apoptotic cells. Interacts with RALBP1 via its effector domain. Interacts with PLXNB1. Probably found in a ternary complex composed of DSCAM, PAK1 and RAC1. Interacts with DSCAM; the interaction requires PAK1. Part of a complex with MAP2K3, MAP3K3, CCM2 and DEF6. Interacts with BAIAP2, BAIAP2L1 and DEF6. Interacts with Y. pseudotuberculosis YPKA and PLCB2. Interacts with NOXA1. Interacts with ARHGEF2. Interacts with TBC1D2. Interacts with UNKL. Interacts with USP6. Interacts with SPATA13. Interacts with ARHGEF16; mediates activation of RAC1 by EPHA2. Interacts with ITGB4. Interacts with S100A8 and calprotectin (S100A8/9). Interacts with PACSIN2. Interacts with ITGB1BP1. Interacts (when active) with PPP5C (via TPR repeats); activates PPP5C phosphatase activity and translocates PPP5C to the cell membrane. Interacts with RAPH1 (via Ras associating and PH domains) (PubMed:18499456). Interacts with MTSS2 (via IMD domain); this interaction may be important to potentiate PDGF-induced RAC1 activation (PubMed:20875796). Interacts with PAK2 (PubMed:20696164). Interacts (GTP-bound form) with SH3RF1 and SH3RF3 (PubMed:20696164). Found in a complex with SH3RF1, MAPK8IP1/JIP1, MAP3K11/MLK3, MAP2K7/MKK7 and MAPK8/JNK1. Interacts (both active GTP- or inactive GDP-bound forms) with SH3RF2 (By similarity). Interacts (GTP-bound form preferentially) with CYRIB (PubMed:31285585, PubMed:30250061). Interacts with DOCK4 (via DOCKER domain); functions as a guanine nucleotide exchange factor (GEF) for RAC1 (PubMed:16464467). Interacts with GARRE1 (PubMed:31871319). Interacts with RAP1GDS1 (PubMed:20709748, PubMed:12551911).
