Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0000455
UniProt IDQ6IMN6
Primary gene name(s)CAPRIN2
Synonym gene name(s)C1QDC1, EEG1, KIAA1873, RNG140

Protein functionMay regulate the transport and translation of mRNAs, modulating for instance the expression of proteins involved in synaptic plasticity in neurons. Involved in regulation of growth as erythroblasts shift from a highly proliferative state towards their terminal phase of differentiation. May be involved in apoptosis. {ECO:0000269|PubMed:14593112}.
