Caprin1 is a protein with 78 kDa. The molecular function is RNA binding and is involved in several biological processes, including negative regulation of translation.
Solomon S., Xu Y., Wang B., David MD., Schubert P., Kennedy D., Schrader JW.(2007). Distinct structural features of caprin-1 mediate its interaction with G3BP-1 and its induction of phosphorylation of eukaryotic translation initiation factor 2alpha, entry to cytoplasmic stress granules, and selective interaction with a subset of mRNAs.
