There are a number of ELISA Kits available for the measurement of karyopherin (importin) alpha 3, another term for the human protein, karyopherin subunit alpha 3. Other synonyms may include: importin subunit alpha-4, SRP1-gamma, importin alpha 4, importin alpha Q2, karyopherin alpha 3 (importin alpha 4), IPOA4, and SRP1. It is encoded by the KPNA3 gene to yield a protein 521 amino acids in length and 57.8 kDa in size. The protein is categorized into the Importin alpha family. Versions of karyopherin (importin) alpha 3 are present in other organisms, including: Mouse, Rat, Fly, Zebrafish, Frog, Chicken.
