Cytoplasmic activation/proliferation-associated protein-1 C term (IPR022070)

Short name: Caprin-1_C

Overlapping homologous superfamilies


Domain relationships



This family of proteins is found in eukaryotes. Proteins in this family are typically between 343 and 708 amino acids in length. This family is the C-terminal region of caprin-1. Caprin-1 is a protein involved in regulating cellular proliferation. In mutated phenotypes, the G1 phase of the cell cycle is greatly lengthened, impairing normal proliferation. The C-terminal region of caprin-1 contains RGG motifs which are characteristic of RNA binding domains. It is possible that caprin-1 functions through an RNA binding mechanism.
