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). {ECO:0000250|UniProtKB:Q5SSG4, ECO:0000269|PubMed:12584248, ECO:0000269|PubMed:24706950, ECO:0000269|PubMed:30665704}. This is the function of ENSG00000270765 (GAS2L2, growth arrest specific 2 like 2).
