– May regulate the transport and translation of mRNAs of proteins involved in synaptic plasticity in neurons and cell proliferation and migration in multiple cell types. Binds directly and selectively to MYC and CCND2 RNAs. In neuronal cells, directly binds to several mRNAs associated with RNA granules, including BDNF, CAMK2A, CREB1, MAP2, NTRK2 mRNAs, as well as to GRIN1 and KPNB1 mRNAs, but not to rRNAs. Caprin-1/CAPRIN1 Protein, Human, Recombinant (His) is expressed in Baculovirus insect cells with N-10xHis tag. The predicted molecular weight is 80.7 kDa and the accession number is Q14444.
