RNA-binding protein that binds to the 3' untranslated region (3'UTR) of target mRNAs (By similarity). Seems to recognize a GAAA motif (By similarity). Can bind to its own 3'UTR, the FOS 3'UTR and the ID 3'UTR (By similarity). Interacts with IGF2BP1 (By similarity). Interacts with MAP1B light chain LC1 (By similarity). Belongs to the RRM elav family.
