Description
General description
Research area: CELL SIGNALING
Product Source: expressed by baculovirus in Sf21 cells
The anaplastic lymphoma kinase (ALK) is a member of the insulin receptor superfamily of receptor tyrosine kinases. The ALK gene is located on human chromosome 2p23 and shares a high similarity with the leukocyte tyrosine kinase (Ltk). ALK is composed of three domains: an extracellular domain responsible for ligand binding, a transmembrane domain that spans the cell membrane, and a cytoplasmic domain housing the tyrosine kinase activity. The cytoplasmic tyrosine kinase domain of ALK plays a significant role in disease pathologies associated with the gene. Within the structure, there are two short conserved β-strands (β7-β8) housing majority of the catalytic residues. Full-length ALK is specifically expressed in the developing central and peripheral nervous systems during embryogenesis and is associated with the balance of cell proliferation and differentiation.

Protein Target: ALK
Target Sub-Family: TK Anaplastic lymphoma kinase (ALK) plays a crucial role in the development of neurons. Binding of ligand to its extracellular domain triggers the activation of the tyrosine kinase that in turn activates the mitogen-activated protein kinase (MAPK) pathway. ALK fusion proteins induce the activation of diverse pathways including Phospholipase C gamma (PLC-γ) and Ras/Extracellular Signal-Regulated Kinase 1/2 (Ras/ERK1/2), which contribute to cell proliferation, while the Janus Kinase/signal transducer and activator of transcription (JAK/STAT) pathway and Phosphoinositide 3-kinase/Protein Kinase B (PI3K/Akt) pathways facilitate cell survival. Notably, ALK has been found to be overexpressed in various human tumors and cell lines such as lymphomas, neuroblastoma, and non-small-cell lung cancer.
