May participate in mRNA transport in the cytoplasm (By similarity). Critical component of the oxidative stress-induced survival signaling. Activates src family kinases and acts as a scaffolding protein enabling src family kinases to phosphorylate and activate PI3-kinase. Binds RNA and promotes the secretion of IGF-II. May play a pivotal role in the progression of scirrhous-type gastric cancer by supporting cancer cell survival in environments with various oxidative stresses. Interacts with PURA (By similarity). Interacts with YES1, SRC, FYN. Upon tyrosine phosphorylation, interacts with PIK3R1. Translocates to plasma membrane upon ultraviolet exposure. Ubiquitously expressed. Highly expressed in scirrhous-type gastric cancer tissues compared with normal gastric mucosa (at protein level). Arg-982 is dimethylated, probably to asymmetric dimethylarginine. Phosphorylated on tyrosine by src family kinases upon ultraviolet exposure. Belongs to the constitutive coactivator of PPAR-gamma family.
