General description

hnRNP-A1 (heterogeneous nuclear ribonucleoprotein) is a pre-mRNA/mRNA binding protein, that belongs to the hnRNP family. It is located in chromosome 12q13.1. It is located in the nucleoplasm but it travels between the nucleus and the cytoplasm. It has two RNP motif RNA-binding domains (RBDs) at the amino terminus and a glycine-rich domain at the carboxyl terminus.


purified human hnRNP-A1.


Anti-hnRNP-A1 has been used in immunofluorescence, immunohistochemistry and western blotting.

Does not immunoprecipitate the hnRNP complex.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, and 15 mM sodium azide.

Biochem/physiol Actions

hnRNP-A1 (heterogeneous nuclear ribonucleoprotein) participates in several RNA metabolisms. It also participates in deep vein thrombosis patients with behçet′s disease. hnRNPA1 mutations results in amyotrophic lateral sclerosis and multisystem proteinopathy.
