DNA-binding protein that seems to act as a transcription factor (PubMed:19584537). Involved in the regulation of neuronal differentiation, acts upon JNK-signaling pathway activation and plays a role in neurite outgrowth in hippocampal cells (By similarity). May mediate with FIBP FGF-signaling in the establishment of laterality in the embryo (By similarity). Promotes cell motility, seems to stimulate tumor metastasis (PubMed:22120713). Cytoplasmic during quiescence, translocates to the nucleus upon stimulation. Expressed in activated T-cells (at protein level) (PubMed:22120713). Expression increases in metastatic tumor cells (at protein level) (PubMed:22120713). By growth factors and 12-O-tetradecanoylphorbol-13-acetate (TPA). Belongs to the IER family.
