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 (PubMed:17289661). Interacts with MAP1B light chain LC1 (By similarity). Brain; neural-specific. Belongs to the RRM elav family.
