Importin4: Proteins and Enzymes

IPO4, also known as Importin-4, consists of a 1,081 amino acid long isoform that is 119 kDa and a shorter 1,083 amino acid isoform that is 119 kDa, and is a nuclear transport receptor for localization signals in between the nucleus and the cytoplasm. This protein has also been shown to have interactions with HIST1H4A, HIST1H4B, HIST1H4C, HIST1H4D, and HIST1H4E. Disease research is currently being studied with relation to IPO4 and leukemia, hypoxia, and pancreatic cancer.
