Anaplastic Lymphoma Kinase Information for Pathologists
Summary:
See also NPM-ALK fusion protein. Anaplastic lymphoma kinase gene is at 2p23; protein is called ALK1, CD246. Membrane spanning tyrosine kinase receptor, member of insulin receptor family. Is NOT the same as Ki-1/CD30, contrary to some references. Interpretation: usually cytoplasmic and nuclear staining.
