Interacts (GTP-bound form) with MICALL1; regulates RAB8A association with recycling endosomes (By similarity). Interacts with MICALL2; competes with RAB13 and is involved in E-cadherin endocytic recycling (By similarity). Interacts (GTP-bound form) with MICAL1, MICALCL, MICAL3, EHBP1 and EHBP1L1; at least in case of MICAL1, MICALCL, MICAL3 and EHBP1L1 two molecules of RAB8A can bind to one molecule of the effector protein; ternary complexes of RAB8A, RAB13 and either MICAL1 or EHBP1L1 are possible (PubMed:27552051). Interacts with EHD1 (PubMed:19864458). Interacts with MAP4K2 and SYTL4 (By similarity). Interacts with SGSM1 and SGSM3 (By similarity). Interacts with RABIF, RIMS2, RPH3A and RPH3A (By similarity). Interacts with OPTN (PubMed:15837803). Interacts with RAB3IP (PubMed:12221131). Interacts with MYO5B (PubMed:21282656). Interacts with PIFO (PubMed:20643351). Interacts with BIRC6/bruce (PubMed:18329369). Interacts with OCRL (PubMed:22543976, PubMed:21378754). Interacts with AHI1 (By similarity). Interacts with DCDC1 (PubMed:22159412). Interacts with LRRK2; interaction facilitates phosphorylation of Thr-72 (PubMed:26824392). Interacts with RAB31P, GDI1, GDI2, CHM, CHML, RABGGTA, RABGGTB, TBC1D15 and INPP5B; these interactions are dependent on Thr-72 not being phosphorylated (PubMed:26824392, PubMed:29125462). Interacts with RILPL1 and RILPL2; these interactions are dependent on the phosphorylation of Thr-72 by LRRK2 (PubMed:29125462, PubMed:30398148). Interacts with DZIP1; prevents inhibition by the GDP-dissociation inhibitor GDI2 (PubMed:25860027).
