Rabbit Monoclonal Antibody to hnRNP A1

hnRNP A1 regulates the alternative splicing of c~Src and c~H~Ras and modifies initiation of translation of the fibroblast growth factor 2 mRNA. hnRNP A1 expression level is elevated in many cancers; knockdown of hnRNP A1 leads to apoptosis in various cancer cells. Although predominantly nuclear, hnRNP A1 is continually transported from the nucleus to the cytoplasm where it disassociates from mRNA and is rapidly re~imported into the nucleus.
