IHC image of ab10303 staining in human pancreas formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab10303, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Product details

Heterogeneous nuclear ribonucleoprotein hnRNPA1 is an abundant nuclear protein that plays an important role in pre-mRNA processing and mRNA export from the nucleus. A1 shuttles rapidly between the nucleus and the cytoplasm, and a 38-amino acid domain, M9, serves as the bi-directional transport signal of A1. Recently, a 90-kD protein, transportin, was identified as the mediator of A1 nuclear import. Transportin mediates the nuclear import of additional hnRNP proteins, including hnRNPF. The nuclear localization of A1 is dependent on ongoing RNA polymerase II transcription.

Supplementary information

Transportin 1 also known as MIP-1 TRN1 or TNPO1 is a protein involved in nuclear transport mechanisms. It functions as a part of the importin-beta family facilitating the transport of cargo proteins into the nucleus by recognizing nuclear localization signals (NLS). Transportin 1 has a molecular weight of approximately 98 kDa and is expressed widely in various tissues. This protein is essential for the nucleocytoplasmic transport operating predominantly in the cytoplasm where it interacts with its cargoes.
Biological function summary

Transportin 1 is an important component in cellular operation by being part of the nuclear pore complex. It mediates the translocation of proteins across the nuclear envelope. The protein plays a role in not just import but also export of numerous cellular regulators and factors influencing gene expression and cell cycle progression. Being part of such complexes places it at the core of many fundamental cellular processes.

Pathways

The actions of Transportin 1 are integral to nuclear-cytoplasmic transport pathways and the Ran-GTPase pathway. It interacts with the small GTPase Ran which provides the necessary energy for active transport and directionality across the nuclear pore complexes. Additionally Transportin 1 shows functional similarity with importin-alpha which expands its role to include overlap in pathway regulation and cargo specificity further embedding it in complex cellular signaling networks.

Transportin 1 has been linked to neurodegenerative conditions and certain cancers. Its role in improper protein transport potentially contributes to the pathogenesis of neurodegenerative diseases like amyotrophic lateral sclerosis (ALS) where mislocalized proteins accumulate improperly. Transportin 1 also associates with the protein TDP-43 known to play a role in ALS and other similar disorders. In cancer abnormal expression of Transportin 1 can alter nuclear transport dynamics affecting tumor suppressor and oncogene distribution thereby contributing to tumorigenesis and cancer progression.

Target data

Functions in nuclear protein import as nuclear transport receptor. Serves as receptor for nuclear localization signals (NLS) in cargo substrates (PubMed : 24753571). May mediate docking of the importin/substrate complex to the nuclear pore complex (NPC) through binding to nucleoporin and the complex is subsequently translocated through the pore by an energy requiring, Ran-dependent mechanism. At the nucleoplasmic side of the NPC, Ran binds to the importin, the importin/substrate complex dissociates and importin is re-exported from the nucleus to the cytoplasm where GTP hydrolysis releases Ran. The directionality of nuclear import is thought to be conferred by an asymmetric distribution of the GTP- and GDP-bound forms of Ran between the cytoplasm and nucleus (By similarity). Involved in nuclear import of M9-containing proteins. In vitro, binds directly to the M9 region of the heterogeneous nuclear ribonucleoproteins (hnRNP), A1 and A2 and mediates their nuclear import. Involved in hnRNP A1/A2 nuclear export. Mediates the nuclear import of ribosomal proteins RPL23A, RPS7 and RPL5 (PubMed : 11682607). In vitro, mediates nuclear import of H2A, H2B, H3 and H4 histones (By similarity). In vitro, mediates nuclear import of SRP19 (PubMed : 11682607). Mediates nuclear import of ADAR/ADAR1 isoform 1 and isoform 5 in a RanGTP-dependent manner (PubMed : 19124606, PubMed : 24753571). Main mediator of PR-DUB complex component BAP1 nuclear import; acts redundantly with the karyopherins KPNA1 and KPNA2 (PubMed : 35446349).. (Microbial infection) In case of HIV-1 infection, binds and mediates the nuclear import of HIV-1 Rev.
