  Function in Host
May regulate the transport and translation of mRNAs ofproteins involved in synaptic plasticity in neurons and cellproliferation and migration in multiple cell types. Binds directly andselectively to MYC and CCND2 RNAs. In neuronal cells, directly binds toseveral mRNAs associated with RNA granules, including BDNF, CAMK2A, CREB1, MAP2, NTRK2 mRNAs, as well as to GRIN1 and KPNB1 mRNAs, but notto rRNAs. [1]
