Product details
While the standard is the same as the one provided in the corresponding SimpleStep ELISA Kit, it cannot be treated as the consumable provided with our SimpleStep ELISA Kit due to differences in its concentration calibration.
Abcam guarantee that this protein standard is suitable for use in a sandwich ELISA. Individual results may vary due to differences in technique, laboratory equipment, buffers, and other experimental factors. The detection range provided for this protein standard is based on initial sandwich ELISA validation data.
The protein concentration is the concentration after validation on our sandwich ELISA platform. This Standard protein is guaranteed to work with our Capture and Detector antibodies in sELISA. Please contact our Scientific Support team to know which antibody pair is suitable for this protein.

Biological function summary
ALK influences cell growth survival and differentiation playing a significant role during the development of the nervous system. As part of its biological activity the ALK protein can become a component of larger signaling complexes participating as an important activator or mediator. Evidence suggests ALK's involvement in neuronal differentiation and synaptogenesis. Its activity impacts intracellular pathways consequently modulating biological processes relevant to neural tissue and oncogenesis.
Pathways
ALK acts within the MAPK and PI3K-AKT signaling pathways. These pathways enable the transduction of signals from the cell surface to the nucleus influencing cellular outcomes such as proliferation and survival. In these pathways ALK interacts with various other proteins including GRB2 and PI3K which further facilitate downstream signaling. Proper functioning of these pathways is essential to maintaining cellular homeostasis and development.

Function
Neuronal receptor tyrosine kinase that is essentially and transiently expressed in specific regions of the central and peripheral nervous systems and plays an important role in the genesis and differentiation of the nervous system (PubMed : 11121404, PubMed : 11387242, PubMed : 16317043, PubMed : 17274988, PubMed : 30061385, PubMed : 34646012, PubMed : 34819673). Also acts as a key thinness protein involved in the resistance to weight gain : in hypothalamic neurons, controls energy expenditure acting as a negative regulator of white adipose tissue lipolysis and sympathetic tone to fine-tune energy homeostasis (By similarity). Following activation by ALKAL2 ligand at the cell surface, transduces an extracellular signal into an intracellular response (PubMed : 30061385, PubMed : 33411331, PubMed : 34646012, PubMed : 34819673). In contrast, ALKAL1 is not a potent physiological ligand for ALK (PubMed : 34646012). Ligand-binding to the extracellular domain induces tyrosine kinase activation, leading to activation of the mitogen-activated protein kinase (MAPK) pathway (PubMed : 34819673). Phosphorylates almost exclusively at the first tyrosine of the Y-x-x-x-Y-Y motif (PubMed : 15226403, PubMed : 16878150). Induces tyrosine phosphorylation of CBL, FRS2, IRS1 and SHC1, as well as of the MAP kinases MAPK1/ERK2 and MAPK3/ERK1 (PubMed : 15226403, PubMed : 16878150). ALK activation may also be regulated by pleiotrophin (PTN) and midkine (MDK) (PubMed : 11278720, PubMed : 11809760, PubMed : 12107166, PubMed : 12122009). PTN-binding induces MAPK pathway activation, which is important for the anti-apoptotic signaling of PTN and regulation of cell proliferation (PubMed : 11278720, PubMed : 11809760, PubMed : 12107166). MDK-binding induces phosphorylation of the ALK target insulin receptor substrate (IRS1), activates mitogen-activated protein kinases (MAPKs) and PI3-kinase, resulting also in cell proliferation induction (PubMed : 12122009). Drives NF-kappa-B activation, probably through IRS1 and the activation of the AKT serine/threonine kinase (PubMed : 15226403, PubMed : 16878150). Recruitment of IRS1 to activated ALK and the activation of NF-kappa-B are essential for the autocrine growth and survival signaling of MDK (PubMed : 15226403, PubMed : 16878150). May function as regulator of gastric epithelial differentiation (By similarity).

Belongs to the protein kinase superfamily. Tyr protein kinase family. Insulin receptor subfamily.
Post-translational modifications
Phosphorylated at tyrosine residues by autocatalysis, which activates kinase activity (PubMed:11121404, PubMed:15938644, PubMed:16878150, PubMed:34819673). In cells not stimulated by a ligand, receptor protein tyrosine phosphatase beta and zeta complex (PTPRB/PTPRZ1) dephosphorylates ALK at the sites in ALK that are undergoing autophosphorylation through autoactivation (PubMed:17681947). Phosphorylation at Tyr-1507 is critical for SHC1 association (PubMed:17274988).. N-glycosylated.
