Anaplastic large cell lymphomas are associated with chromosomal aberrations involving the anaplastic lymphoma kinase (ALK) gene, resulting in the expression of novel chimeric ALK proteins with transforming properties. Many chromosomal rearrangements leading to enhanced ALK activity have been described and are implicated in a number of cancer types (1). A fusion protein of kinesin family member 5B (KIF5B) exon 15 to ALK exon 20 has been reported in a primary lung adenocarcinoma (2). Overexpression of KIF5B-ALK increased cell proliferation, migration and invation via activating the STAT3 and PKB (3).

Product Notes
The KIF5B-ALK (Catalog #AAA516556) is a Recombinant Protein produced from Sf9 insect cells and is intended for research purposes only. The product is available for immediate purchase. AAA Biotech's KIF5B-ALK can be used in a range of immunoassay formats including, but not limited to, Kinase Assay. Researchers should empirically determine the suitability of the KIF5B-ALK for an application not listed in the data sheet. Researchers commonly develop new applications and it is an integral, important part of the investigative research process. It is sometimes possible for the material contained within the vial of "KIF5B-ALK, Recombinant Protein" to become dispersed throughout the inside of the vial, particularly around the seal of said vial, during shipment and storage. We always suggest centrifuging these vials to consolidate all of the liquid away from the lid and to the bottom of the vial prior to opening. Please be advised that certain products may require dry ice for shipping and that, if this is the case, an additional dry ice fee may also be required.Precautions
