Enables proteinase activated receptor binding activity. Involved in several processes, including negative regulation of phospholipase C activity; regulation of signal transduction; and stress granule assembly. Predicted to be located in several cellular components, including centrosome; perinuclear region of cytoplasm; and trans-Golgi network. Predicted to be active in Golgi apparatus and cytosol. Predicted to colocalize with cytoplasmic microtubule. Is expressed in several structures, including gut; heart; nervous system; reproductive system; and sensory organ. Orthologous to human BICD1 (BICD cargo adaptor 1). [provided by Alliance of Genome Resources, Apr 2022]
