Western blot - Anti-ALK(pY1278) antibody [EPR26945-22] - BSA and Azide free (AB305068)

This data was developed using ab305099, the same antibody clone in a different buffer formulation. Blocking and diluting buffer and concentration : 5% NFDM/TBST KARPAS-299 cells carry the NPM-ALK fusion (PMID : 32193476, 9736036). Phosphorylated Tyr338 of NPM-ALK is equivalent to Tyr1278 of full length ALK. Bands around 300 kDa may be due to protein aggregation (PMID : 9121481). Lysates were prepared from fresh material and used for Western blotting immediately to minimize protein degradation. Exposure time : 81 seconds

Supplementary information

This supplementary information is collated from multiple sources and compiled automatically.

The Anaplastic Lymphoma Kinase commonly referred to as ALK is a receptor tyrosine kinase known for its role in cell signaling. It is sometimes called CD246. ALK has a molecular mass of approximately 180 kDa. This protein finds expression predominantly in the central and peripheral nervous system with prominence in neural tissue during development. The ALK protein belongs to the insulin receptor superfamily exhibiting kinase activity that promotes signal transduction processes associated with growth and differentiation.

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.

ALK has a significant relationship with certain types of cancer such as non-small cell lung carcinoma and anaplastic large cell lymphoma. Genetic alterations in ALK such as translocations or mutations can lead to the uncontrolled activation of its kinase activity resulting in oncogenic transformation. In these contexts the ALK protein often interacts with EML4 in lung cancer through a fusion forming an oncogenic driver. Targeting ALK with anti-ALK antibodies or small molecule inhibitors has emerged as a therapeutic strategy to manage these malignancies.

Target data

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).
