Caprin-2 (CAPRIN2)

Promotes phosphorylation of the Wnt coreceptor LRP6, resulting in increased activity of the canonical Wnt signaling pathway (PubMed:18762581). Faciliates constitutive LRP6 phosphorylation by CDK14/CCNY through G2/M stage of the cell cycle, which might potentiate cells for Wnt signaling (PubMed:27821587).

May regulate the transport and translation of mRNAs, regulating for instance the expression of proteins involved in synaptic plasticity in neurons (By similarity). Involved in regulation of growth since erythroblasts shift from a highly proliferative state towards their terminal phase of differentiation (PubMed:14593112).
