General description

Monoclonal Anti-hnRNP-A1 (mouse IgG2a isotype) is derived from the 4B10 hybridoma produced by the fusion of mouse myeloma cells (SP2/0 cells) and splenocytes from NZB mice immunized with purified human hnRNPA1. Heterogeneous nuclear ribonucleoprotein A1 (hnRNPs) consist of protein groups named A to U and many of these protein groups consist of more than one isoform. The major steady-state proteins of the isolated hnRNP complex are A1, A2, B1, B2, C1, and C2, with a range of molecular weight starting with 34 kDa up to 43 kDa. hnRNP-A1 is ubiquitously expressed in cells and tissues.

Immunogen

purified human hnRNP-A1.

Application

Applications in which this antibody has been used successfully, and the associated peer-reviewed papers, are given below.
Western Blotting (1 paper)
Monoclonal Anti-hnRNP-A1 antibody produced in mouse has also been used in:
  • enzyme linked immunosorbent assay (ELISA)
  • immunoblotting
  • immunoprecipitation
  • immunocytochemistry.

Biochem/physiol Actions

Heterogeneous nuclear ribonucleoprotein A1 (hnRNP-A1) is important in biological activities such as transcription, pre-mRNA processing, cytoplasmic mRNA translation and turnover. hnRNP-A1 is important in pre-mRNA processing and in mRNA export from the nucleus. The protein contains a 38-amino acid domain called M9, which is important for the interaction with the transportin protein and therefore, for its import and export from the nucleus. RanGTP mediates dissociation of hnRNP-A1 from transportin. Higher expression is observed in proliferating and/or transformed cells than in differentiated tissues.

Physical form

Aberrant miR-21 expression is closely associated with cell proliferation, anti-apoptosis, migration, invasion, and metastasis in various cancers. However, the regulatory mechanism of miR-21 biogenesis is largely unknown. Here, we demonstrated that the tumor suppressor PTEN negatively regulates the expression of

Familial dysautonomia (FD) is a severe genetic disorder causing sensory and autonomic dysfunction. It is predominantly caused by a c.2204+6T>C mutation in the IKBKAP gene. This mutation decreases the 5' splice site strength of IKBKAP exon 20 leading to exon
