Involved in the cross-linking of microtubules and microfilaments (PubMed:12584248, PubMed:24706950). Regulates microtubule dynamics and stability by interacting with microtubule plus-end tracking proteins, such as MAPRE1, to regulate microtubule growth along actin stress fibers (PubMed:24706950). Enhances ADORA2-mediated adenylyl cyclase activation by acting as a scaffold to recruit trimeric G-protein complexes to ADORA2A (By similarity). Regulates ciliary orientation and performance in cells located in the airway (PubMed:30665704). Interacts with ADORA2A (via its cytoplasmic C-terminal domain) (By similarity). Interacts with GNAS, GNAL, GNAQ, and GNA13 (PubMed:23994616). Interacts with MAPRE1 (PubMed:24706950). Colocalizes with ADORA2A at neuronal processes (By similarity). Colocalizes with and tracks the tips of microtubule plus ends (PubMed:24706950). Expressed in bronchial and nasal epithelial cells (at protein level) (PubMed:30665704). Expressed in brain, kidney, lung, testis, fallopian tubes, and skeletal muscle (PubMed:12584248, PubMed:30665704). Expressed at low levels in stomach and colon (PubMed:30665704). The disease is caused by variants affecting the gene represented in this entry. Absence of GAS2L2 results in ciliary orientation defect and affects performance of cilia. Belongs to the GAS2 family.
