Alternative Name HnRNP core protein A1 / HNRNPA1 (HNRNPA1 Antibody Abstract)
Background RNA polymerase II trans cripts in the nucleus are in complex with several proteins calledheterogeneous nuclear ribonucleoproteins (hnRNPs). These proteins are important inbiological activities such as transcription, premRNA processing, cytoplasmic mRNAtranslation, and turnover. hnRNPs can be isolated either by immunoprecipitation or bysucrose gradient fractionation of cell extracts.2, 4, 5 Isolated hnRNPs consist of proteingroups named A to U and many of these protein groups consist of more than oneisoform. The major steady-state proteinsof the isolated hnRNP complex are A1, A2, B1, B2, C1, and C2, with a range ofmolecular weight starting with 34 kDa up to 43 kDa.2, 4, 5 hnRNP-A1 is important inpre-mRNA processing and inmRNA export from the nucleus. The protein binds to its RNA target through aconsensus RNA-binding site UAGGGU. The protein contains a 38-amino acid domaincalled M9, which is important for the interaction with the transportin protein andtherefore, for its import and export from the nucleus. RanGTP mediatesdissociation of hnRNP -A1 from transportin. hnRNP-A1 is ubiquitously expressed with ahigher expression in proliferating and/or transformed cells than in differentiated tissues.6.

Format Liquid
Concentration 2 mg/mL
Buffer 0.01 M PBS, pH 7.4, Sodium Azide
Preservative Sodium azide
Precaution of Use WARNING: Reagents contain sodium azide. Sodium azide is very toxic if ingested or inhaled. Avoid contact with skin, eyes, or clothing. Wear eye or face protection when handling. If skin or eye contact occurs, wash with copious amounts of water. If ingested or inhaled, contact a physician immediately. Sodium azide yields toxic hydrazoic acid under acidic conditions. Dilute azide-containing compounds in running water before discarding to avoid accumulation of potentially explosive deposits in lead or copper plumbing.
Handling Advice Avoid freeze-thaw cycles
