RNA-binding protein that binds to the 3' untranslated region (3'UTR) of target mRNAs (PubMed:8668530). Seems to recognize a GAAA motif (PubMed:8668530). Can bind to its own 3'UTR, the FOS 3'UTR and the ID 3'UTR (PubMed:8668530). Interacts with IGF2BP1 (By similarity). Interacts with MAP1B light chain LC1 (PubMed:21288476). Brain; neural-specific (PubMed:8668530). Expressed in the hippocampus (PubMed:11573004). Up-regulated after memory training in radial arm maze experiments. Belongs to the RRM elav family.
