Detailed entry information

Protein Information (annotations from UniProt)

Database IDHIV0001349
UniProt IDP09651
Primary gene name(s)HNRNPA1
Synonym gene name(s)HNRPA1
Protein nameHeterogeneous nuclear ribonucleoprotein A1
Protein functionInvolved in the packaging of pre-mRNA into hnRNP particles, transport of poly(A mRNA from the nucleus to the cytoplasm and may modulate splice site selection. May play a role in HCV RNA replication. {ECO:0000269|PubMed:17229681}.
Subcellular locationNucleus. Cytoplasm. Note=Localized in cytoplasmic mRNP granules containing untranslated mRNAs. Shuttles continuously between the nucleus and the cytoplasm along with mRNA. Component of ribonucleosomes. In the course of viral infection, colocalizes with HCV NS5B at speckles in the cytoplasm in a HCV-replication dependent manner.
